Copper slag is an industrial by-product material produced from the process of ... partial andor full replacement for fine aggregate in normal and high strength concrete mixtures. The following were specific tasks

Mechanical Properties Of Recycled Aggregates Concrete

The material passing through 4.75 mm sieve size is termed as fine aggregates. Natural sand or crushed sand is usually mainly as fine aggregates in concrete mixes. 1.2.1 NATURAL AGGREGATE Aggregates can come from either natural or manufactured sources. Natural aggregates come from rock, of which there are three broad geological classifications.

Properties Of Concrete Made With Recycled

M4 were obtained by replacing 10, 12.5, 15 and 17.5 of the mass of cement by silica fume, respectively Sarkhel, 2000 Allen, 1997. In the concrete mix CC, no mineral admixture was added and fully natural fine aggregate is used but in all other four mixes 40 of fine aggregate is replaced by artificial sand. Comparing

Study On Characteristic Strength Of Partially Replaced

Cubes, beams and cylinders were casted by partial replacing natural coarse aggregate by 25, 30, 35, 40, 45 and 50 of manufactured fly ash aggregate. The strength parameters such as compressive strength, flexural strength and split tensile strength of the casted cubes, beams and cylinders were tested respectively.

The Maintenance Repair And Replacement Of Historic Cast

The replacement of natural stone with cast stone requires careful attention to selection of fine aggregates and the pigmentation of the cementing matrix. Coarse aggregate, which is generally used in cast stone to control shrinkage and assure adequate compressive strength, can present an aesthetic problem if it is visible at the surface of cast ...
