Mix Design and Pumped Concrete By KAUSHAL KISHORE Materials Engineer Roorkee A simple method of concrete mix design for pumpable concrete based on an estimated weight of the concrete per unit volume is described in the paper The tables and figures presented are worked out by the author from a wide range of Indian materials.

Mix represents concrete with designated proportions of cement sand and aggregate And the number following M represents compressive strength of that concrete mix in N/mm 2 after 28 days For example for M20 grade of concrete mix its compressive strength after 28 days should be 20 N/mm 2 .

Mix Design SCC looks very different from conventional concrete while mixing Concrete producers must retrain their eyes for this very fluid mixture as it turns corners and fills forms Traditionally concrete with the fluidity of SCC has had a very high water to cement ratio which would lower compressive strengths and compromise

strength concrete mix designs with sand comprising only 39 of the to tal aggregate volume In some paving mixes it has been as low as 34 However in other locations where the coarser aggregate is the only kind available or for several other reasons the balanced sand content may be as high as 48 Cement type and source

Concrete 1 bag Sand Epoxy 2 gallons Water 5 gallons Tip Do not add too much water to the concrete at the beginning of the mixing process If the mixture is too runny it will not adhere well to the crack Additional water can be added to the mixture at the end if needed Concrete can be mixed with epoxy to repair cracks.

Concrete mix designs are submitted for review so that the reviewer can verify the contractor is interpreting the construction documents correctly These guidelines were developed to assist the engineer reviewing concrete mix designs The main body of the guidelines focuses on the process of reviewing the mix design.

Standard mixes of the fixed cement sand and aggregate ratio which ensures adequate strength are termed nominal mixes Standard mixes offer simplicity and under normal circumstances have a margin of strength above that specified. However because of the variability of mix ingredients the nominal concrete for given workability varies widely in strength.
