Portland cement is produced by mixing ground limestone, clay or shale, sand and iron ore. This mixture is heated in a rotary kiln to temperatures as high as 1,600 degrees Celsius. The heating process causes the materials to break down and recombine into new compounds that can react with water in a crystallization process called hydration.
Concrete Sand is coarse in nature and primarily used in the manufacture of ready mix concrete and asphalt.

9. Two physical characteristics give reinforced concrete its special properties: The coefficient of thermal expansion of concrete is similar to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction. When the cement paste within the concrete hardens, this conforms to the surface details of the steel, permitting any stress to be …

Water/Cement Ratio The number of pounds of water per pound of cement. A low ratio means higher strengths, a high ratio means lower strengths. For NCDOT, the ratio depends on the class of concrete, whether an air agent is used or not, and the shape of the stone - rounded or angular.
In a mixing container, add no more than 1 part cement to 2 parts sand. For some applications, you may add up to a 1:8 ratio of cement to sand. More cement means more strength and stickiness but less workability. Ratios with more cement than a 1:2 ratio with sand will prove difficult to work with and some of the aggregate may not bind correctly.

2. • A cement is a binder, a substance used in construction that sets, hardens and adheres to other materials, binding them together. Cement is seldom used solely, but is used to bind sand and gravel (aggregate) together. Cement is used with fine aggregate to produce mortar for masonry, or with sand and gravel aggregates to produce concrete.
