The thought of using C1157 and C989 SLAG Cement and being.. green.. , was far from anyone s mind.. ASTM C1157 is manufactured under a.. Performance Specification.. in contrast to the prescriptive C150 Portland Cement specification.. This allows for a target of 10% calcium carbonate (limestone) and a lower CO2 footprint.. To give the new silo the longest possible life cycle, SLAG CEMENT was introduced to the concrete design.. The concrete proposed for the silo was 60% C1157 and 40% Slag cement with a low water cement ratio.. A hundred year durable concrete can be expected with this combination of cementitious materials.. The C1157 from Leeds is a Type HE, MS (High Early, Moderate Sulfate) cement.. All this was proposed to the slip form contractor TEI (T.. E.. ibberson Company).. TEI is an experienced slip form contractor, but had no familiarity with doing a complicated slip form with this combination of cementitious materials.. A support team was formed that included the concrete supplier, Sherman Industries, TEI, and Heidelberg Technology Center (HTC), to monitor the concrete performance of the slip.. The results of the first phase of the silo were a successful slip form concrete placement of 1554 cubic yards at an average rate of 11 vertical inches per hour.. This rate of placement is considered good for the complexity of the formwork and reinforcing.. Hydraulic pump pressures that jack the slip formwork were reported to be low normal and the concrete had no tendency for stickiness..

  • Title: For Precast and Block, Slag Makes Sense
    Descriptive info: News.. Type IS blended cement.. combines portland and slag cements into a single product form.. For concrete producers with limited silo capacity, blended cement allows them to achieve benefits of using slag cement in concrete—like greater strength and durability—without multiple silos.. A Type IS blend performs similarly to a Type I portland cement and conforms to ASTM C595, “Standard Specification for Blended Hydraulic Cements.. ”.. Family business refines products with blended cement and gains “green” customers.. Lael Libera started using a blended slag/portland cement in his concrete products to achieve a number of benefits: greater strength, less cracking, better color.. Now Libera’s company, Cromwell Concrete Products, is one of the only producers in New England using slag cement in concrete masonry units, and his business is thriving because of it.. Boosting quality in block, and opening doors with precast.. The company has used a blended portland-blast furnace slag cement (Type IS, 65% portland, 35% slag) for about two and a half years.. One of the biggest benefits of incorporating the blended product is a reduction in cracking during block processing: Libera says there are fewer cracks than with a straight portland cement mix.. Rich Sullivan, territory manager for supplier Lehigh Northeast, says that “the material is filling the mold better, and is more consolidated.. ” While some cracking is normal during concrete block production, Libera’s blocks routinely go through the processing machinery without cracking.. The slag cement is also allowing Libera to produce lighter-colored blocks with smoother finishes, as well as great-looking split-face blocks.. Because of the company’s success with slag cement in block, Libera says it was natural to try it in precast applications.. “We do architectural work—coping, wall caps, and window sills—so  ...   “green” products that include recycled content and byproducts.. “When you use a byproduct, that’s a good thing,” explains Libera.. “You’re getting a better product, using less cement and less natural resources that create cement, and using up a byproduct that you wouldn’t have had a use for before.. ”.. Jan Prusinski, executive director of the Slag Cement Association, says that, “using slag cement in block and precast is an ideal way to increase the environmental sustainability of a structure.. ” SCA offers a new publication, the LEED-NC™ 2.. 1 Guide: Using Slag Cement in Sustainable Construction, that “shows how slag can help achieve green building certification using the U.. Green Building Council’s LEED green building rating system.. ” (.. Click here to download the publication.. Cromwell Concrete Products is even using blended cement in work for the Connecticut Department of Transportation (DOT), which requires concrete to include incorporated byproducts.. Libera says the material’s lighter color and cleaner finish are ideal for curbing and barrier projects where high visibility is an important safety attribute.. More in Store for the Future.. Libera says his experience with slag cement has opened up more possibilities.. Soon the company will add a new silo for unblended slag cement, to achieve greater control of mix designs.. Also, they plan to use slag cement as they develop self-consolidating concrete (SCC) mixtures; slag cement adds “fines” to SCC which is an important paramater in SCC proportioning a successful SCC mixture..

  • Title: Mobile Mix Business Gets Boost From Blended Cement
    Descriptive info: Mobile Mix Business Gets Boost From Blended Cement.. Type IS, paired with focused technical service, a good fit for small but healthy industry segment.. Don Mullin doesn’t mess around when it comes to concrete.. As owner of Concrete Express, a Salem, Conn.. -based mobile mix provider, his business is on the line with every load of cement delivered.. Unlike ready-mix operations, which have the ability to roll through a “false set” problem or a cement product that characteristically absorbs water at a faster rate, “We in the mobile mix industry are very sensitive to any cement product changes because we only have a nine-foot mixing cycle,” says Mullin.. “We’ve got to be right on the first pass.. We can’t put more water in and then take it out again—once you’re a pickle, you can’t be a cucumber again,” he jokes.. Mobile mix operations are ideally suited for small jobs.. The operations combine all the necessary equipment and materials on one truck, mixing the concrete on-site: the concrete ingredients are conveyed into a nine-foot auger, which mixes the material at the location, supplying loads as small as a quarter of a yard.. With smaller delivery equipment, they can squeeze into tight job site areas, supplying loads as small as one yard to complete projects like deck piers, equipment pads, sidewalks and other small projects.. So when Rich Sullivan, territory manager for supplier Lehigh Northeast, approached Mullin with the idea of trying a load of the company’s Type IS portland blast furnace slag blended cement in place of conventional portland cement, Mullins replied: “you’ve got to be out of your mind.. ” With his one-silo business, there would be no margin for error.. Customized service sells.. Mullin was more than a little skeptical of using the type IS cement, but Sullivan guaranteed the product and offered to pull it from the silo if it didn’t work.. “Don was having false-set problems with a regular portland mix, as were five or six of the other mobile mix guys in the area,” says Sullivan.. “I explained that he wouldn’t have the same problem with the blended cement, because the  ...   the field, Mullin uses high-tech mobile mixers from Elkin Manufacturing Inc.. , which have the ability to meter and volumetrically dispense the cement at a consistent rate, ensuring precise product.. The Lehigh Type IS is inter-ground, and Sullivan says that in the summer months, the target range is 33 to 35% slag; in the colder months, the range is reduced slightly to 30 to 33% slag.. “The beauty of the inter-ground material is that the slag granules are harder than cement clinker, so by the time the ball mills get the slag to the desired fineness, the cement blaine has gone from a typical Type I portland blaine to a Type III high early blaine,” explains Sullivan.. “The high early characteristic of the finer-ground cement provides earlier strength gain to a blend that would otherwise have seemed destined for delayed strengths because of the reduction of portland cement content.. Non-traditional product serving a traditional market.. The result: Mullin has been using Type IS for more than two years, and five more mobile mix companies in the area have converted to Type IS.. “It’s a really good product,” says Mullin.. “Like peanut butter and jelly, it’s a good merger—individually, they’re both decent products in the right application.. ” He is quick to say that he thinks mobile mix operators should see for themselves if the product is a good fit for their specific needs.. But for him, it works: “The IS product has significantly reduced bleed water and is more manageable, and achieves a higher strength gain.. The blend is more predictable than [ordinary] portland cement, and as long as they seasonally adjust it, it’s a superior product,” says Mullin.. Solid customer service really cinched the deal, he adds.. Even with an excellent product, “you have to go back to basics with the sales of everything.. ” In a market where people don’t like change, providing the right level of technical support will help producers improve their product and expand the market.. “Work with people, monitor your results, and prove yourself,” he says, and the business will come to stay..

SCA member companies supply over 95 percent of the slag cement in the U.. Click here to download a listing of member company sales offices, arranged by state.. These sales offices will be able to let you know about the availability of slag cement in your area.. Slag cement use can be traced to the 1700’s when the material was combined with lime to make mortars.. The first United States production was in 1896.. Until the 1950’s, granulated slag was used in the manufacture of blended portland cements, or as raw feedstock to make cement clinker.. However, in the 1950’s, slag cement became available in.. Slag cement is most widely used in concrete, either as a separate cementitious component or as part of a blended cement.. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and  ...   slag.. What are the enviromental benefits of using slag cement?.. Production of slag cement creates a value-added product from a material—blast furnace slag—that otherwise might be destined for disposal.. Not only does the making of slag cement lessen the burden on landfills, but it also reduces air emissions at steel plants through the granulation process (as compared to the traditional air cooling process).. What specifications govern the use of slag cement in concrete?.. Slag cement, when used as a separate component in a concrete mixture, is specified through ASTM C 989 Specification for Ground Granulated Blast-Furnace Slag for Use in Concrete and Mortar.. When used as a component in blended cement, one of two specifications are used: ASTM C595, Specification for Blended Hydraulic Cements or ASTM C1157,.. How much slag cement do I include in a concrete mixture?.. The amount of slag cement added to a concrete mixture, as a percentage of cementitious material by weight, normally ranges from 20 to 80 percent..
