RECYCLED TIRES AS COARSE AGGREGATE IN CONCRETE

PDF Aggregates for Concrete - Memphis

Recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. Conven- Size numbers (grading sizes) for coarse aggregates apply to the amounts of aggregate (by mass) in percent-ages that pass through an assortment of sieves (Fig. 5-5).

Mechanical behavior of recycled aggregate concrete-filled

The compressive mechanical behaviors of recycled aggregate concrete-filled steel tube (RACFST) stub columns after exposure to elevated temperatures were experimentally investigated in this study. The RACFST stub columns incorporating different recycled coarse aggregate (RCA) replacement ratios of 0, 50% and 100% were heated under elevated

Applicability of recycled aggregates in concrete piles for

The strength of concretes with natural aggregates was compared with the strength of concretes with recycled (fine and coarse) aggregates. Results show that all samples met the minimum compressive strength specified for compaction piles used to improve the bearing capacity of soft soils.

Water Permeability Properties of Concrete made from

Water Permeability characteristic of concrete made from recycled brick concrete as coarse aggregate was investigated and compared with concrete made from crushed clay brick and natural stone aggregate. For this, concrete samples of three different compressive strengths 17.2, 20.6 and 24.1 MPa were prepared as per ACI mix design methods from each of these aggregates.
