compressive strength for these concrete grade 10 15

approximately about 70% of the grade strength of the concrete and For 28 days test result the strength to be gain by approximately 100 % of the grade strength of the concrete Normally the unit of compressive strength as KG/SQMM N/SQMM As per thumb rule at the time of weighing the cubes the minimum weight of cubes are 8 6 kg The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall " Number of samples for testing Compressive Strength

Compressive strength of concrete cube test provides an idea about all the characteristics of concrete By this single test one judge that whether Concreting has been done properly or not Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures

The grade of concrete is understood in measurements of MPa where M stands for mix and the MPa denotes the overall strength Concrete mixes are defined in ascending numbers of 5 starting at 10 and show the compressive strength of the concrete after 28 days For instance C10 has the strength of 10 newtons C15 has the strength of 15 newtons

Determination of appropriate mix ratios for concrete grades using Nigerian Cement grades Concrete grade Compressive strength Portland-limestone cement Introduction concrete which is taken as the 28 days crushing strength of concrete cubes or cylinders [15]

Compressive Strength of Concrete

Compressive strength of concrete ( اختبار مقاومة الضغط للخرسانة) Out of many test applied to the concrete this is the utmost important which gives an idea about all the characteristics of concrete and Compressive Strength of it

The strength of concrete depends on the materials you use sooo many factors Some Coarse aggregates have better crushing strength giving your concrete better strength Some aggregates fail soon Depends on grade of cement 33 43 53 grades Those ratios are just nominal mixes you can get higher or lower strength depending on the materials

High Strength Concrete (Compressive Strength M60) is used in High rise structures (30 floors) collect the following data before hand as few design stipulation are freezed on the basis of these data (Considered same as M55 grade for High Strength Concrete) = 60 + 1 65 x 5 0 = 68 25 N/mm2

Average compressive strength = 22 7Mpa The average compressive strength of the two kinds of concrete are compared in figure 4 and figure 5 Figure 4 This chart shows the comparative strength of concrete containing crushed rock aggregate and concrete with natural aggregate concrete for M15 Grade 0 5 10 15 20 crushed rock aggregate concrete

Feb 13 201520 7 Comparison between Modern and Classic Method Concrete Compressive Strength Testing with Press and Rebound Hammer Advantages of testing the compressive strength of concrete with two methods 1 The NDT method with the rebound hammer 2 the classical method by crushing specimens A
