Feb 01, 2009 The results proved that up to 15% of fines content in crushed sand could be used without adversely affecting concrete strength. However, little work has been done so far on the effect of fines in crushed sand on the durability of concrete. This paper examines the influence of limestone fines in crushed sand on concrete properties

Get PriceJun 11, 2020 Crushed sand is very abundant in limestone quarries and its use could significantly decrease the materials cost of concrete, eliminate the dust disposal cost, reduces environmental pollutions and dilapidation of natural resources
Get PriceFor concretes with constant water-cement ratio, incorporation of VFS resulted in significant reduction in slump. Although the compressive strength of natural sand concrete was not significantly affected by the incorporation of VFS, crushed stone sand concrete indicated an increase in strength
Get PriceThis paper describes the effects of high temperatures on the strength characteristic of crushed limestone sand concrete (CLSC). To compare, natural (river) sand concrete (NSC) and CLSC specimens were exposed to the three different high temperatures. Visual color-change and weight loss were also carefully examined through the tests. The test results indicated that the decreasing rate of
Get PriceJan 01, 2016 However, relevant researches are concentrated on mechanical or permeability properties of crushed limestone sand concrete [3,11,12], and effects of such CS characteristics on property of CSC, especially frost durability, have been little investigated yet
Get PriceAbstract The construction industry has developed at the pace as human race. With time many materials were developed to be used in construction. Among all the materials concrete has been tested, researched and used for almost every type of construction. Sand is a basic component of concrete. With increase in concrete production and usage the sand dredging also increased at an alarming rate
Get PriceFeb 10, 2021 This paper presents the fresh and hardened properties of high-strength concrete comprising byproduct fine crushed aggregates (FCAs) sourced from the crushing of three different types of rocks, namely granophyre, basalt, and granite. The lowest void contents of the combined fine aggregates were observed when 40% to 60% of natural sand is replaced by the FCAs. By the

Get Price3. Concrete Sand. Concrete sand consists of granite rock, gneiss, or limestone. This sand has angular granules and works best when mixed with cement. Besides usage in concrete, concrete sand can also be used in bedding pipes. This type of sand is usually crushed in a quarry and filtered severally to remove huge fragments and large rocks
Get PriceCrushed Limestone. There is no naturally formed rock that is as versatile as limestone – especially when it’s been crushed and screened. Paired with its strength, durability, and practicality, crushed limestone has become a “go-to” material for landscaping, home-improvement, and construction projects

Get PriceJul 30, 2018 The increase in unit weight of concrete, due to the incorporation of steel slag aggregate, in lieu of crushed limestone aggregate, was approximately 17%.Though the compressive strength of SSA concrete was marginally better than that of crushed limestone aggregate concrete, no significant improvement in the flexural and split tensile strengths
Get PriceIn this study, the workability, the compressive strength and the water penetration depth under pressure for concrete incorporate with quarry waste as fine aggregate were investigated. The mix proportions of concrete were set into two classes of water to cement ratio (w/c = 0.4, 0.6). The first class (C1), the mix proportion is 1.0:0.6:2.0:4.0 (Cement: Water: Fine: Coarse)
Get PriceThe aim of this study is to investigate the effects of incorporating dune sand as fine aggregates replacement in self-compacting concrete. Twelve mixes were cast and tested for both fresh and hardened properties. The mixes were divided into 2 groups: Each group comprised six mixes. The constituent materials were as follows: Normal Portland cement CEM Ι 42,5N, dolomite as coarse
