Effect of modulus of elasticity of coarse aggregate on strength of this concrete has not yet been established. But a disputable thing is that as concrete behave as a monolithic material, aggregate having low value of modulus of elasticity will yields less bond stress with matrix. In case of high performance concrete, it is considered beneficial.

synthetic man made sand called manufacture sand can also be used in place of course aggregates and fine aggregates. Due to even size of all particles in Msand, high content of reactive silica in Msand and higher density of Msand give better properties to the concrete mix compared to conventional concrete.
Natural sand does not require more water to enhance the workability of the mixture so the amount of bleed water in the concrete will not be increased. Manufactured sand or manufactured fine aggregate (MFA) is produced by reducing larger pieces of aggregate into sandsized aggregate particles.

Ultrahigh performance concrete has a discontinuous pore structure that reduces liquid ingress, significantly enhancing durability compared to conventional and highperformance concretes. UHPC is being considered for use in a wide variety of highway infrastructure applications.
HighStrength Concrete: Its strength is greater than 5,800 psi. To make this form of concrete, the water to cement ratio is less than .35. Sand is used as the aggregate and silica fume is added for additional strength. HighPerformance Concrete: This is highstrength concrete with additional chemicals added for wear resistance and durability ...
Polaris is well established as a significant supplier of high quality concrete aggregates in northern California, including from its Richmond Terminal as well as via customerterminals and recently initiated sales in Los Angeles via its Long Beach concrete aggregate products are also utilized in Hawaii, Vancouver, and Alaska.

River sand (RS) and crushed rock fine (CRF) have been used as fine aggregate in concrete for centuries. However, dredging river beds for RS is now banned in many places due to its adverse environmental impacts. On the other hand, CRF has the major problems of being angular in shape and containing excessive fines. To resolve these problems, the technology of processing CRF to .
