Concrete Mix Design Using Crushed Sand

The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The compressive strength obtained is same as of normal mixes.In fact use of crushed sand will become inevitable in near future because of dwindling sources of natural sand. Crushed sand particle though shaped, does not have the

Influence of Aggregate Grain Size on the Formulation of

1. Introduction. Over the past 40 years, the use of sand concrete has become more and more common. Indeed, this material made from sand, cement, water and other admixtures tries to replace traditional common concrete in certain construction fields (bricks, cinder blocks, roughcasts, paving stones, low-stress structures, etc.), not only because of the rarity of gravel in certain areas, but also

Microstructure and Mechanical Behavior of Concrete Based on

The aim of this work is to reduce the overexploitation of river sand by proposing a combination of crushed sand and river sand to develop an optimal mix design for concrete. The approach used consisted of a physical, chemical, and mineralogical characterization of aggregates from three quarries located in Yaoundé (Cameroon), followed by the formulation of concrete by substituting 100%

PDF The Use of Ceramic Tile Waste as Aggregate in Concrete

The reference concrete mix was made withconventional coarse and fine aggregates (crushed stone and natural sand). Five mixes were prepared incorporatingcoarse ceramic aggregate as partial substitute of coarse aggregate with replacement levels of 10%, 20%, 30%, 40%, and 50%. Besides, five mixes incorporated fine crushed ceramic as partial

Behaviour of Concrete on Replacement of Sand with Quaries

3. Santhosh Kumar.P.T et al made an attempt to study the effect of type of fine aggregate on the 28 day compressive strength of concrete. The result of the investigation indicate that the ratio of the 28 day compressive strength of concrete with crushed stone sand to that of river sand is 1.06 with a coefficient of variation of 11 %.

Effects of crushed stone dust on some properties of concrete - ScienceDirect - ScienceDirect.com | Science, health and medical journals

Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve. Effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well.

Crushed Sand vs. Natural Sand: Make the Right Choice!

Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Crushed sand contains a larger amount of micro- fine particles. This can affect the strength of concrete.

Influence of Local Sand on the Physicomechanical Comportment

This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune (SD) on sustainability of high performance concrete (HPC) in aggressive environments. The experimental study shows that the parameters of workability of HPC are improved when the CS is partially replaced by the SD (<2/3). However
