sand particles and maintain good workability. Well-rounded gravel will have better workability with finer sand, which is needed to fill the sma ller void areas. These ideal conditions are seldom found and the mix design requires adjustments to compensate for variations from the ideal conditions.

Properties of Concrete Concrete is an artificial conglomerate stone made essentially of Portland cement, water, and aggregates. Properties of Concrete While cement in one form or another has been around for centuries, the type we use was invented in 1824 in Britain. It was named Portland cement because it looked like the

Concrete mixing ratios for cement, sand, aggregate, and water are generally mixed as 1 part cement, 3 parts sand, and 3 parts aggregate or stone with just enough water to make it workable. CONCRETE MIXING RATIOS. When making concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mix.

The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical.

· High-performance Mix Design for Concrete Countertops ... Fine aggregate: I use sand made for concrete (conforming to ASTM C ) rather than gap-graded sand in my wet-cast. Concrete sand conforming to ASTM C is readily available at ready-mix producers or sand quarries. It contains a range of sizes.

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
