The word concrete comes from the Latin word quotconcretusquot that means compact or condensed in fact it is well known that since the second century the Romans mixed quicklime with pozzolan to enhance its hydraulic properties and then mixed it with aggregates in order to obtain a robust stone-like material for the construction of roads and structures.
Rate for crushing concrete cubes. A Simple Guide to Concrete Cube Testing QEM Solutions. Jul 24, 2018 Concrete is one of the most widely used building materials in the world, yet . onthe cubes till they fail, the rate of loading is 0.6 177 0.2 MPas Nmm178s. is acompressive requirement of 50 Nmm178 for a crushed concrete cube.
The acceptance criteria of quality of concrete is laid down in IS456-2000. The criteria is mandatory and various provisions of the code have to be complied before the quality of concrete is accepted. In all the cases, the 28-days compressive strength shall alone be the criterion for acceptance or rejection of the concrete. In order to get a relatively quicker idea of the quality of concrete, optional test for 7 days compressive strength of concrete be carried out.
6 Cubes of 150 x 150 x 150 mm size the nominal size of aggregate does not exceed 38 mm shall be cast, 3 for 7-days testing and 3 for 28-days testing. A set of3 cubes specimen average strength will be a sample. The individual variation of a set of 3 cubes should not be more than 15 of the average. If more, the test result of the sample is invalid.
Note- For aggregates larger than 38 mm, bigger than 150 mm moulds are to be used. See IS10086-1982CUBE MOULDThe cube moulds of required size 150 mm for nominal size of aggregate not exceeding 38 mm shall be made in such a manner as to facilitate their separation into two parts. Cube moulds shall be provided with a base plate and they shall be as per IS10086-1982. The dimensions, tolerance and materials of cube moulds shall be as given in table-1.

TAMPING RODAs per IS10086-1982, the tamping rod shall be 160.5 mm dia and 6002 mm long with a rounded working end and shall be made of mild steel.
A Simple Guide to Concrete Cube Testing. The cubes are generally tested at 7 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.
4 Factors to Consider When Purchasing the Crusher . Nov 25, 2019 For example, jaw crusher can combine with cone crusher, impact crusher, or hammer crushing to building a complete crushing line, so that to improve the grade of finished products. Feeding method it should be considered so that to choose the supporting feeding equipment.
Sampling should be spread over the entire period of concreting and the frequency of sampling of concrete of each grade shall be as following.

The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions. Concrete mix can be designed or proportioned to obtain the required engineering and durability properties as required by the design engineer. Some of the other engineering properties of hardened concrete includes Elastic Modulus, Tensile Strength, Creep coefficients, density, coefficient of thermal expansion etc.
The compressive strength of concrete is determined in batching plant laboratories for every batch in order to maintain the desired quality of concrete during casting. The strength of concrete is required to calculate the strength of the members. Concrete specimens are a cast and tested under the action of compressive loads to determine the strength of concrete.
In very simple words, compressive strength is calculated by dividing the failure load with the area of application of load, usually after 28 days of curing. The strength of concrete is controlled by the proportioning of cement, coarse and fine aggregates, water, and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio, the higher is the compressive strength.
The capacity of concrete is reported in psi 8211 pounds per sq. inch in US units and in MPa 8211 mega pascals in SI units. This is usually called as the characteristic compressive strength of concrete fc fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa. For certain applications and structures, concrete mixes can be designed to obtain very high compressive strength capacity in the range of 500Mpa, usually referred as Ultra High Strength Concrete or Powder Reactive Concrete.
8220The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days fck. 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.8221.
