BS 8500 is the British Standard for specifying and producing concrete. It is the complementary British Standard to BS EN 206. BS 8500 is split into two parts. Part 1 covers specification and gives guidance to the specifier. Part 2 covers the constituent materials in concrete and contains the information required by the concrete producer.

Even small deviations from the standard procedures will usually lead to compressive strength results which are lower than the true strength of the concrete. For example, for each 1% air entrapped there will be a 4 to 5% loss of strength. The procedures for concrete cube making are given in British Standard (BS) 1881:1983 Testing Concrete. Equipment

The 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 IS:10086-1982. The dimensions, tolerance and materials of cube moulds shall be as given in table-1.

Standard tests for determining the strength are Cube Test and Cylinder Test. As the name suggests, the difference in both the tests are in the shape of test specimens. In Indian, British and European standards, the Compressive strength of concrete is determined by testing concrete cubes referred as characteristic compressive strength whereas in ...

Slump-test (British Standard) This European standard specifies a method for determining the consistence of fresh concrete by the slump test. The slump test is sensitive to changes in the consistence of concrete, which correspond to slumps between 10 mm and 200 mm. Beyond these extremes the measurement of slump can be unsuitable and other ...

can be based on one test cube/cylinder per sample. The acceptance criteria are: • individual tests (f ci ≥ (f ck – 4) MPa) • tests are also assessed either in groups of three (mean f cm ≥ f ck + 4) MPa) or groups of at least 15 (mean f cm ≥ f ck + 1.48σ) MPa, where σ is the standard deviation). Annex B covers ‘identity testing ...

Cube moulds are usually 150mm x 150mm x 15 mm (or 100mm x100mm x100mm) and can be made from steel or polyurethane. The cube moulds must be manufactured to the specifications / standards of the relevant body, in the UK it is the British Standards …

May 14, 2020· But the British standard mainly uses the cube strength as characteristic strength to represent the concrete in the design formulas. Therefore, knowing the relevant strength classes or the relationship between the structure are important. As it appears, there is no linear relationship between the cube strenth and the cylinder strength.

It is the standard test, to determine the tensile strength of concrete in an indirect way. This test could be performed in accordance with IS : 5816-1970. A standard test cylinder of concrete specimen (300 mm X 150mm diameter) is placed horizontally between the loading …

A standard cylinder is 150mm diameter by 300mm high and a standard cube is 150mm size. BS EN 206-1, Table 7 and Table 8 link the compressive strength determined using 100mm cubes to values of compressive strength for 150mm cubes. Although cube strength will continue to be used as a basis for supply in the UK, it is important

Never use nonabsorbent cube or cylinder molds for this purpose. Strength of other types of grout is determined using 2 in. cubes per ASTM C 942. Method C 942 allows for field preparation, recognizes fluid consistency, and also affords a means for determining compressive strength of grouts that contain expansive agents or grout fluidifiers.
