Mix design of CRD concrete Concrete with strength of 30 MPa (M30 grade) designed as per latest BIS code, IS 10262: 2009 [7] was considered as control concrete (C30) mix. The mix proportion of CRD concrete arrived at was (Cement: Fine aggregate: Coarse aggregate) 1:1.59:3.27 with 0.4 as water to binder ratio.

This work is devoted to the study of fresh and hardened properties of concrete containing recycled gravel. Four formulations were studied, the concrete of reference and three concretes containing recycled gravel with 30, 65 and 100 % replacement ratios. All materials were formulated on the basis of S4 class of flowability and a target C35 class of compressive …

Destructive tests on concrete as a replacement of fine aggregates with stone quarry dust revealed that there is an upsurge of compressive resilience by 6.7% [11], 10.56% [12], 22% [13], 22.76% [14 ...

In the study, a mix of M30 grade concrete was used and designed as per the guidelines of IS 10,262 2009 [33]. 10, 20, 30, and 40% of fine aggregates were replaced with crushed limestone dust in the concrete mix.Water-cement ratio and content of cement were kept constant (0.462 and 430 kg/m 3 respectively) in the study. Coarse aggregates of only two …

The granite quarry dust was sourced from Justmoh Quarry, located at Essipon (4.9706° N, 1.6919° W), near the Western Regional Capital of Ghana. Cement and fine and coarse aggregates underwent testing for various properties to conduct the …

Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates.

Accordingly, Trial Mix design of M25 grade concrete was carried out using crushed stone dust after fulfilling the physical properties as per the relevant standard. Several trials were …

HMA mix design is the process of determining what aggregate to use, what asphalt binder to use and what the optimum combination of these two ingredients ought to be. When aggregate and asphalt binder are combined to produce a homogenous substance, that substance, HMA, takes on new physical properties that are related to but not identical to the ...

Because suggested limits for aggregate gradation vary depending on the type of mix design being developed, only a few examples are given hereâ a complete listing of aggregate gradation requirements are given in the various chapters discussing mix design procedures for the various HMA mix types: dense-graded HMA, gap-graded HMA, and open-graded ...
