Crushed rock sand An economical and ecological alternative to

The admixture dosage was increased from 0 to 1% and the slump values were measured. The slump values for concrete manufactured using NS and 100% replacement with CRS were plotted (Fig. 1).The plots reveal that at low level of admixture dosage (upto 0.70%), the concrete manufactured using CRS as 100% fine aggregates 2.2.2 Concrete Mixture The mix ratio used for the experiment was 1:2:4 (cement: fine aggregate: coarse aggregate) by weight, the water/cement ratio was 0.6. The fine aggregate was replaced with WG at 15%, 25%, 35%, 45% and 50% partial replacement for sand. For each replacement level,PERFORMANCE OF CONCRETE WITH PARTIAL REPLACEMENT OF

Use of waste glass as aggregate and cement replacement in concrete

Cairns, Queensland, to demonstrate the use of RGS in concrete as coarse sand replacement. Concrete with 40% RGS achieved the characteristic strength of 32 MPa at 28 days. The footpath has been used successfully for a year. The successful application of using recycled glass in concrete can reduce sand dredging andWKA of Concrete WKA of different mixes was determined by using the slump test and CF test as per the test procedure laid down in IS 1199-1959. To examine the low or medium WKA, both Slump and CF test were performed for workability. The effect of the addition of SD as partial replacement of natural sand on WKA of concrete is shown Utilization of Stone Dust as an Effective Alternative for Sand

Characteristics of Cement Mortar with M-sand as Replacement

Natural sand obtained from river bed is conventionally used as fine aggregates in preparation of cement mortar. Present study investigates flow and strength characteristics of cement mortar at various replacement levels of alternative fine aggregate, M-sand. Plastering mortars (1:3 and 1:4 ratio) were prepared with natural Due to this criterion, QD powder may now be partly utilized in concrete, which is a useful use [50].
