What tests are conducted to determine the strength of concrete?
+ What is meant by slump? + What are admixtures? + What are plasticizers? Will the strength of concrete be affected by the addition of these plasticizers? What is concrete? concrete is a composite building material made from the combination of aggregate and a cement binder. The most common form of concrete consists of Portland cement, mineral aggregates (generally gravel and sand) and water. What is aggregate? Aggregate is the component of a composite material used to resist compressive stress. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel. What is cement? Cement is a material used for bonding other materials together, and as a binder in concrete. The term cement is most commonly used to refer more specifically to powdered materials which develop strong adhesive qualities when combined with water. These materials are more p
