Mix design for recycled aggregate pervious concrete

2020-10-30 · This paper demonstrates that RSM can be used to design the mix proportion of recycled aggregate pervious concrete. From the perspective of the internal structure of recycled permeable concrete, the factors affecting its strength and porosity are the paste properties, the coating thickness of paste on the surface of aggregate and the void content of aggregate.

New Mix Design Method for Recycled Concrete Using

2020-5-2 · This study proposes a new mix design method for C30 recycled concrete using recycled aggregate crushed from different strength source concrete (SC). The dosages of cement, water, sand, and coarse recycled concrete aggregate (CRCA) are the same as the corresponding components in natural concrete, but the CRCA should be pre-wetted before casting.

Concrete Mix Design for Completely Recycled Fine

The undesirable properties of conventional recycled fine aggregate (RFA) often limit its application in the construction industry. To overcome this challenge, a method for preparing completely recycled fine aggregate (CRFA), which crushes all concrete waste only into fine aggregate, was proposed. The obtained CRFA had high apparent density, and its water absorption was lower than that of the ...

Aggregates - Portland Cement Association

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.

Aggregate Moisture in Concrete| Concrete

2013-5-31 · I design my mixture with aggregates in the saturated surface-dry (SSD) condition. { Answer } The moisture condition of aggregates in concrete is very important. We are all familiar with Abrams Law, which states that, all other things being equal, compressive strength of concrete is dependent on the ratio of mass of water to cementitious material.
