The present study focuses on the effects of microsilica at various percentages as a partial cement replacement in concrete with overburnt bricks as coarse aggregates. The mechanical properties of hardened concrete such as splitting tensile strength, flexural strength and compressive strength are studied and analyzed.

While the type of admixtures, cement and aggregate have an effect on the compressive strength of the concrete, the water to cement ratio is the primary factor affecting the strength. As the water to cement ratio decreases, the compressive strength of the cement increases.

The results indicate that the concrete having over burnt bricks as aggregates may be termed as medium light weight concrete having a density between kg/m3 and that by reducing the watercement ratio from 0. 6 to 0. 4 increases the compressive strength from by more than 30%.

workability, the brick aggregates concrete requires greater proportion of water than the normal concrete. Use of broken over burnt bricks as coarse aggregate for structural concrete is recommended when natural aggregate is not easily available, high strength of concrete is not required and the bearing capacity of the soil is low.

Using Fine Recycled Concrete Aggregate for Mortar Production situation occurred in the Silva, Bavaresco6 et al. 4 and Pedrozo8 studies. Most studies consulted found that water retentivity of fresh mortar made with recycled aggregates was lower. Since .

Concrete has relatively high compressive strength, but significantly lower tensile ... 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ... of concretes with abnormally high compressive strengths between 340 and 410 ... much higher than typical high .

A simple design office oriented empirical model containing only two parameters has been developed to predict creep behavior of concrete made of crushed clay bricks as coarse aggregate. For this, concrete samples having three different normal compressive strengths in the range of up to N/mm2 are first prepared and then tested for their creep deformation.

Compressive Strength of Bricks. (i) Compressive Strength of first class brick is 105 kg/cm 2. (ii) Compressive Strength of 2nd class brick is 70 kg/cm 2. (iii) Compressive Strength of common building brick is 35 kg/cm 2. (iv) Compressive Strength of sun dried brick is 15 to 25 kg/cm 2.

Concrete Brick: It is made of concrete. It is the least used bricks. It has low compression strength and is of low quality. These bricks are used above and below the damp proof course. These bricks are used can be used for facades, fences and internal brickworks because of their sound reductions and heat resistance qualities.

splitting tensile strengths) of concrete containing waste brick ballast and marble ballast were well comparable to those of the concrete ithout brick ballast. The production of normal aggregates and building stones through quarrying is an expensive process. Quarrying involves deep excavation and blasting of rocks.

Jun 13, 2017· This study investigates the compressive strength of high strength concrete produced with powdered burnt brick as partial replacement for cement at different water cement ratio. it aimed to investigate the feasibility of using waste bricks powder in high strength concrete.

Jul 12, 2016· Concrete and things made from concrete or cement tend to have fantastic compressive strength. Often it is measured in the thousands of pounds per square inch range. But the same material typically has only onetenth the strength when you apply a tension or stretching force to it. Bending a poured concrete or concrete block wall creates tension.

The concrete specimens that made of crushed floor tiles, crushed bricks, and crushed concrete aggregate were termed as tile concrete (TC), brick concrete (BC) and crushed aggregate concrete (CAC). The result for all specimens has shown good workability with slump ranging from 5185 mm. BC showed optimum brick replacement of 17% with the 28day compressive strength of 36 N/mm2.

brick tends it to be use as thermal insulation. Stone dust bricks as waste material can be used for manufacturing brick which give high compressive strength as compare to other bricks. In market stone dust and fly ash is a waste material this also made the brick economical as compared to .

possible to conserve natural resources and to decrease energy used in production. In some ... MdZulfiqar Ali Khan Evaluation of the Compressive strength of Concrete for partial replacement of Over Burnt Brick Ballast Aggregate, ISSN:, Volume2, Issue1, December 2013 ...

Tensile testing machine, Brick strength testing machine, Computerized compression testing machine are the instruments used. Compressive strength of burnt clay bricks is determined by compressive test.

The compressive strength of cylindrical concrete specimens made with different replacement ratios (0%, 25%, 50%, 75% and ) of brick aggregate by IFS aggregate is shown in Figure 3. It can be seen from Figure 3 that compressive strength of concrete increased up to 50% replacement of BC by IFS aggregate.

the strength of brick aggregate concrete was investigated experimentally by Rahman et al. (2009). It was reported that moistcured brick aggregate concrete show significant higher compressive strength in comparison with that of the aircured concrete. An average value of the ratios of the compressive

fines concrete of low density, mainly for block production, to structural concrete with densities from 1000 to 2000 kg/m3 and compressive strength up to 80MPa. There have been difficulties pumpingLWAC because the pump pressures forces water into the porous .

properties of surkhi there is a gradual increase in compressive strength in earlier stages and gradual decrease of compressive strength is obtained in later stages, this may be attributed to high bleeding and shrinkage properties of surkhi. Not only the compressive strength of the bricks but also the other

Flexural and Compressive Strength. Flexural strength is a measure of the tensile strength of concrete. It is a measure of the ability of an unreinforced concrete beam or slab to withstand failure in bending. It is measured by loading 150x150mm concrete beams with a span length at least three times the length.
