The technical center also conducts a variety of environmental-related analyses by meticulously following applicable EPA methods.
The technical center provides vital, value-added services to the cement manufacturing plants, customers and markets we serve. For Ash Grove Cement’s customers in need of customized technical service, it delivers timely, responsive support to:
For Ash Grove cement manufacturing plants, the tech center consistently helps the production facility to:
Every day, Ash Grove’s technical service managers are in the field helping our customers solve the common – and uncommon – challenges that may arise with their construction projects.
As materials and field experts, our technical service managers have in-depth knowledge and experience with cement and concrete properties and construction practices. They are capable of expedited problem identification, along with providing technically meaningful and pragmatic solutions to get your projects back on track.
While some are LEED-certified, all of Ash Grove’s technical service managers are LEED-educated and work with our customers to achieve their project’s environmental goals. These experts can advise on a wide variety of building materials and project solutions including:
Ash Grove’s technical service managers are actively involved in local and national cement and concrete technical associations, including the American Concrete Institute and ASTM International.
Ash Grove Cement is constantly innovating product solutions to meet an emerging industry need or meet needs unique to your project. These are some of the Ash Grove products proven to meet the most common, or challenging, situations.
Type I-II meets the specification requirements for both ASTM C150 Type I and Type II, the most widely used cement for many kinds of concrete construction.
Available in the West, Midwest and Texas.
This cement provides high strengths at an early age. It is chemically and physically similar to Type I cement, except that its particles have been ground finer. It is used when forms need to be stripped as soon as possible or when the structure must be put into service quickly.
Available in the West and Midwest
This type of cement gains strength more slowly than Type I cement and is used primarily in concrete exposed to severe sulfate attack - where soils or groundwaters have a high sulfate content. This cement is particularly effective for structures such as sewage treatment plants and septic tanks.
Available in the Western United States.
Durabase® uses CKD (cement kiln dust) and is effective in soil stabilization projects, extending the service life of our nation’s roads and parking surfaces. Formerly landfilled, creating a high-value use for this product is part of Ash Grove’s overall commitment to sustainable development.
Duracem® F is an ASTM C595 blended cement that also meets ASTM C1157 performance specifications. It is made with interground Class F fly ash. Note, the fly ash addition rate varies.
Durapoz® F is a performance-enhanced pozzolan made with Class F fly ash for high-performance concrete. The product is designed to mitigate alkali silica reactivity and provide exceptional sulfate resistance. It helps reduce chloride permeability while attaining improved ultimate flexural and compressive strengths.
DURA SLAG® is a slag cement which has latent hydraulic cement properties. Using slag cement as a partial replacement of the portland cement can enhance plastic and hardened properties of concrete. DURA SLAG® meets specifications in ASTM C989 Grade 120 and AASHTO T302.
Lab tests show our products have excellent bond strength and adhesion with masonry units, resulting in less droppage waste and high water retention that resists rapid loss of moisture from the mortar, reducing the need for retempering.
This hydraulic cement is comparable to ASTM Type I cement and is typically used in shallower applications of oil well cementing.
Ash Grove Packaging offers a full array of products designed for residential, commercial and industrial use. Ash Grove Packaging supplies packaged concrete mix, cement, mortar, stucco and other related construction products through its facilities in Arkansas, Mississippi, Tennessee, Oklahoma, Kansas, Nebraska and Utah, with headquarters in Little Rock, Arkansas. More innovation, more care, more production leads to increased overall value, improved communities and better lives for our customers, our workers and our nation.
In 1824, an English bricklayer patented the product. He called it "portland" cement because he thought it resembled natural building stone found on the Isle of Portland in the south of England. Today, portland cement, stone, sand and water are the basic ingredients of the concrete products with which we build highways, bridges, commercial buildings, dams, residential homes and many of the other structures fundamental to America’s economic vitality and quality of life.
The Portland Cement Association provides information on cement and concrete basics.
The modern manufacturing process required to produce portland cement requires complex equipment and machinery, efficient consumption of heat and energy and sophisticated computer and instrumentation technology. Throughout the process, each step is carefully monitored and tested to ensure that the finished product meets our quality specifications and that the environmental effects of our operation are in compliance with governmental regulations.
