equipment of the slag alkali cement

Alkali-activated slag mortar samples were immersed in 5% Na 2 SO 4 solution for up to 90 days. At the same time, control samples of alkali-activated slag were cured in humid chamber, and Portland-slag cement (CEM II) was used as a benchmark material

alkali silica reaction - slag cement
alkali silica reaction - slag cement

Slag cement contains a small amount of alkalis.Typically, the amount of alkali is similar to that of low- to-moderate-alkali portland cement (for example, 0.5 to 0.7% Na 2 O equivalent). Some guide specifications and standard practices, such as AASHTO PP65-11, 5 allow the option of limiting the alkali content of concrete when reactive aggregates are used

Mar 01, 1999 · The major advantages of slag replacement of OPC in making concrete is the superior durability and lower heat of hydration as compared to 100% OPC binder. However, the low early strength of these concretes is a limitation in many applications. The problem of low early strength can be overcome by using alkali activated slag (AAS) as the type of

Calcium carbide slag is a by-product from the chlor-alkali chemical industry, from hydrolysis of calcium carbide (CaC 2) for an acethylene gas, polyvinyl chloride, polyvinyl alcohol and other industrial production. It contains high amounts of calcium compounds and has the potential for replacing the traditional raw material, limestone, for cement production
