results in dense and cohesive concrete thus increasing the strength and life of the concrete. Manufactured sand is popularly known by several names such as crushed sand, rock sand, green sand, robo sand, poabs sand, barmac sand, pozzolana sand, and artificial sand. The term manufactured sand is used for
This 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 ...

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.
a viable solution for the replacement of river sand [8, 9]. M-Sand is a crushed aggregate produced from hard granite stone which is rough, flaky shaped with sharp edges, washed and graded with consistency to be used as a substitute of river sand. The mechanical and durability properties of concrete incorporating M-sand is enhanced
May 14, 2015· Several concrete mixes were prepared with 100 % recycled aggregates and the results were compared to that of a control mix. SEM was conducted to examine the microstructure of selected mixes. The results showed that concrete with acceptable strength and durability could be produced if high packing density is achieved.
Factors affecting durability of concrete 27th January 2010 14th March 2016 Concrete durability has been defined by the American Concrete Institute as its resistance to weathering action, chemical attack, abrasion and other degradation processes.
The influences of fines content, methylene blue () value, and lithology of crushed sand (CS) on frost durability and strength of concrete were investigated, and the frost durability and strength of crushed sand concrete (CSC) and river sand concrete (RSC) were compared. The results show that inclusion of fines improves CSC compressive strength and reduces frost durability of C30 CSC when ...

Factors Affecting Strength of Concrete. Concrete strength is affected by many factors, such as quality of raw materials, water/cement ratio, coarse/fine aggregate ratio, age of concrete, compaction of concrete, temperature, relative humidity and curing of concrete.
Too much water reduces concrete strength, while … river gravel crushed recycled concrete used for normal concrete … STUDY ON STRENGTH AND DURABILITY OF CONCRETE BY PARTIAL … aggregate in place of conventional river sand concrete production. … Khatib, A. Aït-Mokhtar, Strength and Durability of Concrete Incorporating Crushed Limestone Sand.
Strength and durability of concrete incorporating crushed limestone sand. In recent years, there is a growing interest in the use of crushed sand obtained from limestone quarries in some countries where river sand is not widely available. The fines content is usually high in crushed sand which can adversely affect concrete properties.

Home / Concrete Technology / CONCRETE MIX DESIGN USING CRUSHED SAND The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
Crushed stone sand has been identified as a potential substitute material for natural sand in making good quality concrete. The main objective of the present investigation is to determine an adequate mix design method and evaluate engineering properties of crushed limestone sand concrete mixtures in both the fresh and hardened sates.
increase in compressive strength with crushed sand. The compressive strength was increased by 19.44 % to 40.38 % at 7 days age and increased by 8.33% to 25.9% at 28 days age as grade of increased mixes was increased. The flexural strength of concrete with crushed sand was marginally increased about 1 to 5% as compared to natural sand.
The compressive aggregate strength is an important factor in the selection of aggregate. When determining the strength of normal concrete, most concrete aggregates are several times stronger than the other components in concrete and therefore not a factor in the strength of normal strength concrete.
Crushed Sand vs. Natural Sand: Make the Right Choice! ... The compressive strength as well as the flexural strength of concrete made from Crushed sand are higher than natural sand. ... It gives higher durability and strength to concrete by overcoming deficiencies like segregation, bleeding, honeycombing, voids and capillary. ...
The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and durability, strength, and uniform appearance of the hardened concrete while being economical.
