Effect of Aggregate-Cement Ratio on Engineering Properties ...

Future Scope. The study could further be extended by varying and introducing more parameters like grading in coarse aggregate. Use of other cementitious material like ultra fly ash cement, pozzolana with rice husk and formation of new pervious concrete by use of old recycled pervious concrete etc. and quantify their effect on overall permeability, compressive strength and porosity.

ACI mix design - Memphis

Volume of dry-rodded coarse aggregate per unit volume of concrete for different coarse aggregates and fineness moduli of fine aggregates ACI Mix Design 8. Estimation of fine aggregate content-- There are two standard methods to establish the fine aggregate content, the mass method and the volume method. We will use the "volume" method.

Aggregate in Concrete - Concrete Network

An optimized gradation based on aggregate availability and project requirements will result in an economical concrete with good workability and finishability. The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired.

Recycled Aggregates - Portland Cement Association

The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being reconstructed. Recycling of concrete is a relatively simple process.
