    Material properties. Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar – a binder mixed with water that hardens over time. The aggregate varied, and included pieces of rock, ceramic tile, and brick rubble from the remains of previously demolished buildings. Gypsum and quicklime were used as binders. Volcanic dusts, called pozzolana or "pit sand", were favored

  • High-Strength Concrete Portland Cement Association

    Manufacture of high-strength concrete involves making optimal use of the basic ingredients that constitute normal-strength concrete. Producers of high-strength concrete know what factors affect compressive strength and know how to manipulate those factors to achieve the required strength.

  • Effects of Aggregate Properties on Concrete Size, Grading

    Strength of concrete is also affected by the properties of coarse aggregates besides water-cement ratio and other properties. The lower the water to cement ratio, the more the effect of coarse aggregates on the strength of concrete. Undesired properties of coarse aggregate may affect the strength, durability, and performance of concrete negatively.

  • Recommended Concrete Mix Proportions – Know the Concrete

    The ingredients have their different individual properties. Strength, workability and durability of the concrete depend heavily on the concrete mix ration of the individual ingredients. Since the process of concrete formation is an unidirectional chemical reaction, concrete gets its different properties all together. Related Readings

  • Concrete Design & Production Portland Cement Association

    Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. The material's unique combination of superior properties and design flexibility facilitated the architect's ability to create the
