Oct 20, 2014 . Degree of workability = 0.8 compacting factor. Grade of cement = OPC 53. Specific gravity of cement = 3.15. Specific gravity of sand = 2.6. Specific gravity of aggregate = 2.6. Maximum size of aggregate = 20mm. 1. Target mean strength for mix design. The target mean compressive strength at 28 days is.

Sep 4, 2013 . Thank you. that was a great info. ignore those repeater id*ots saying about safety wherein this is just a very small scale experiment. Dirty hands are sign of good labor anyway.. Read more. Show less. Reply 3 4. Diptayan Dey2 years ago. The mode of failure of the cube is not satisfactory.. Read more.

Based on the existing experimental data for compressive strength values of different concrete mixes, a statistical analysis for the gathered data was conducted. The analysis revealed a model for predicting the compressive strength of concrete mixes at any age with the help of two constants (A) and (B) that are considered as.

Jun 30, 2016 . The compressive strength is quantified for varying percentage and grades of concrete by replacement of sand with quarry dust. .. (d)In the fourth series, M20, M30, and M40 grades of concrete with 20, 30, and 40 percent replacement of quarry dust with water-cement ratio of 0.45 are studied and the results.

is made in this research by partially replacing the natural sand with M-Sand. To study the basic strength and durability characteristics of concrete, M30, M40 and M50 grades were selected. In the strength characteristic study, the compressive strength, split tensile strength and flexural strength were determined experimentally.

Experimental Investigation on Compressive. Strength of M30 and M40 Grade of Concrete with Partial Replacement of Robo Sand by. Natural Sand and Cement by Flyash. T.Shobha 1, M.Mujahid Ahmed 2. P.G. Student, Department of Civil Engineering, Geethanjali College of Engineering & Technology, Kurnool, India1.

properties of the concrete. In the main stage the M40 grade concreate mix design is done utilizing IS: 10262:2009 without Nano silica or with replacement of nano silica at 1%, 2%, 3% and 4% dosage by weight of cement. The compressive strength and flexure strength is determine by universal testing machine. Keywords:.

experimental study on the compressive strength of ordinary grade of concrete such as M20, M30, M40 and M50 subjected to thermal cycles at a temperature of 50º C. The experimental program on concrete specimens of size 100 x 100 x 100 mm cubes were cast for testing compressive strength. The test specimens.

system was named alkali resistance glass fibre reinforced concrete. In the present experimental investigation the alkali resistance glass fibres has been used to study the effect on compressive, split tensile and flexural strength on M20, M30, M40 and M50 grades of concrete. Keywords: glass fibres, strength properties,.

crushing strength of m40 concrete,### investigations on mechanical properties of high strength silica fume .

To investigate the mechanical properties i.e., compressive strength, splitting tensile strength, flexural strength and modulus of elasticity of concrete at different replacement levels of cement with silica fume for the selected grades of concrete. 3. SCOPE OF THE PRESENT WORK. High-strength concrete of grades M40 and.

Dec 14, 2017 . temperatures are loss in compressive strength, loss in weight or mass, change in color and spalling of concrete. The objective of this research attempt was to prove experimentally the effects on the behavior of concrete under elevated temperatures of different grades (M20, M40 and M60) of concrete.

domestic waste water as mixing and curing water for Mix M2 Similarly average compressive strength results of M40 grade concrete cast by using Tap water as mixing and curing water for Mix M3 & treated domestic waste water as mixing and curing water for Mix M4. Discussion of results covers, M20 grade concrete at the.

strength of 36 MPa or less which is defined as nor- mal strength concrete, a number of experiments have revealed that Eq. 1 over-estimates the modulus of elasticity as the compressive strength increases (Fig- ure.1). This study aims to derive a practical and uni- versal equation which is applicable to high-strength concretes.

In all, 13 different mixtures with a constant water/binder ratio of 0.36 and grade M40 were prepared by using ordinary Portland concrete alone, or with partial . The results of testing revealed that the addition of 10 per cent SF was found to result in the greatest increase in compressive strength and flexural strength along with.
