Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during production of concrete etc. Test for compressive strength is carried out either on cube or cylinder.

Committee, under whose direction this British Standard was prepared, ... method for determining the compressive strength of concrete cubes. NOTEThe titles of the publications referred to in this Part of this standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of this standard the definitions given in BS5328 and BS5497-1 apply. 3 Apparatus 3.1 Testing ...

strength of various classes of concrete, was obtained,(El-Reedy, (2009)). The compressive strength for each (w/c) ratio are mathematically represented by three equations each one represent the relation between (compressive strength, age of

For example, class M30 (C25/30 as per British Standards) is the concrete having a characteristic compressive cube strength of 30 N/mm 2. The same concrete would have a characteristic strength of 25 N/mm 2 at 28 days if cylinders were used for testing, as in certain European countries.

2019-05-17 Reinforced concrete should be specified as class Cl0,40 except for concrete made with cement conforming to BS 402710 (SRPC), which should be specified as class Cl0,20. Post-tensioned elements in an internal building environment may also be specifed as class Cl0,10.

Actual compressive strength values predicted ones at different ages for different concrete mixes. Applicability of the model for mixes containing mineral admixtures Fig. 8 shows the relationship between age and compressive strength for mixes containing 0%, 12%, 16%, 20%, 24% and 28% silica fume as a percentage replacement by cement mass [17] .

The compressive strength of concrete depends on the water to cement ratio, degree of compaction, ratio of cement to aggregate, bond between mortar and aggregate, and grading, shape, strength and size of the aggregate (Roccoand Elices, 2009; Elices and Rocco, 2008).

Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.

2016-09-26 I am having more than 20 years experience in the field of QA/QC in civil engineering construction technology. From my experience in various R D and experiment for hardened concrete latest technology which i strongly recommended for compressive strength in structure CUT PULL OUT TEST, ASTM C900.
