The objective of this paper, is to present the results of experimental investigations on physical and mechanical properties of concrete made with coarse and fine crushed bricks aggregates. Natural aggregates (coarse, fine or both) are substituted by weight by crushed bricks at rates varying from 0, 25, 50, 75 or 100%.

Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete. It is manufactured by crushing the quarried stone to a size that will completely pass through 4.75 mm sieve.

Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher dusts or small crushed sand samples on concrete properties [8,12,13]. However, little work has been performed on the complete replacement of natural fine aggregate in concrete with crusher dusts. In response to this, this study investigated a range of sands produced by an industry

Mar 16, 2019 Typically, it takes 34% less washed m-sand than VSI crusher fines to mix good quality concrete. The average flexural strength is also improved with washed m-sand, boasting 1.8 N/mm compared to VSI crusher fines’ 0.89 N/mm . Importantly, when it comes to cracking, testing shows that the crusher fine-mortar ring displays uneven texture and

Several concrete samples were prepared with 0%, 10%, 20% and 100% replacement levels of crushed stone sand substituted for fine aggregate. All these concrete samples are tested for compressive, flexural and split tensile strength test after curing for 7 days, 14 days, 28 days and 56 days to examine the variation in the mechanical performance of concrete. An optimum mix is obtained for 20%

In this paper, we are interested in microstructure analysis of hydraulic concrete using crushed basalt, crushed gneiss and alluvial sand as fine aggregate. Our work consists to use X-ray diffraction (XRD), enthalpy thermal analysis (HDSC) and thermogravimetric analysis (TAG) to identify chemical and mineralogical behavior of microstructure of various concrete and then explain their mechanical

Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.

AGGREGATES. Fine and coarse aggregates make up the bulk of a concrete mixture. Sand, natural gravel and crushed stone are used mainly for this purpose. Recycled aggregates (from construction, demolition and excavation waste) are increasingly used as partial replacements of natural aggregates, while a number of manufactured aggregates, including

It is also worth mentioning here that crushed fine aggregates normally outperform natural sand when the most essential hardened concrete properties, such as compressive and tensile strength, are compared. At the same time, the problems of achieving economical mixes with suitable workability (fresh state properties of concrete) are normally reported as the main problem that can render the use

Crushed stone dust or natural sand is the fine aggregate chiefly utilised in the concrete mix. Sand may be collected from the river, sea, lake or pit. Still, when used in the concrete mix, it should be adequately cleaned and tested to determine that the total percentage of silt, salts, clay and other such organic stuff does not pass the defined limit.
