Pervious concrete is a special type of concrete with a high porosity, made from a mixture of cement, water, coarse aggregate and a minimal amount of fine aggregate (sand). Pervious concrete creates a porous medium, which allows water from precipitation and other sources to pass through and reach the underlying soil. This reduces runoff from a site while recharging groundwater levels. Pervious concrete has applications in sustainable construction, and is often used in sidewalks, parking areas, and greenhouses.

High-strength ready mix concrete is a specialized type of concrete designed to have a higher compressive strength than standard ready mix concrete. It is commonly used in applications where the structure will be subjected to heavy loads or where a higher level of durability is required.

The mix design of high-strength ready mix concrete typically includes a higher proportion of cementitious materials, such as cement and supplementary cementitious materials (SCMs) like fly ash, slag cement, or silica fume, to increase its strength. The use of aggregates with high crushing strength is also common.

In addition to the mix design, the curing conditions for high-strength ready mix concrete are critical to achieving the desired strength. Proper curing requires maintaining a consistent temperature and humidity level to ensure the concrete reaches its full strength potential.

Self-compacting concrete (SCC) is a type of concrete that is highly fluid and can flow into place and fill the formwork without the need for vibration or external compaction. SCC is typically made with a similar mix design as conventional concrete but with a higher proportion of fine aggregates and cementitious materials to ensure high flowability and deformability.

SCC is designed to have a high deformability, allowing it to flow and fill complex formwork and congested reinforcement without the need for external vibration. This makes it easier and more efficient to place concrete in difficult to access areas or where there are obstructions. SCC can also improve the quality of the finished concrete by reducing the risk of honeycombing and voids, as well as improving the surface finish.

SCC can be used for a wide range of applications, including building foundations, walls, columns, precast elements, and civil engineering structures such as bridges and tunnels. It can also be used in situations where vibration is not possible or would be disruptive, such as in hospitals or residential areas.
