Get Priceconcrete, is to enable a concrete technologist to design a concrete mix for a particular strength and durability. The conditions that prevail at the site of work, in particular the exposure condition, and the conditions that are demanded for a particular work for which the mix is designed.
Get PriceThe volume of mix is sufficient to produce 3 numbers of cube and to carry out the concrete slump test. The volume of mix is multiplied with the constituent contents obtained from the concrete mix design process to get the batch weights for the trial mix. The mixing of concrete is according to the procedures given in laboratory guidelines.
Get Price• The effects are larger for the concrete mix with slump = 30 mm and smaller for the concrete mix with slump = 180 mm • The compaction effort has significant effects on the 7-day and 28-day cube strengths • The effects are larger for the concrete mix with slump = 30 mm and smaller for the concrete mix with slump = 180 mm

Get PriceTRIAL BATCH METHOD In the trial batch method of mix design, use actual job materials to obtain mix proportions. The size of the trial batch depends upon the equipment you have and how many test specimens you make. Batches using 10 to 20 pounds of cement may be big enough, although larger batches produce more accurate data.

Get PriceConcrete Quantity Required for Trial Mix. Volume of 1 cube mould = 0.150 x 0.150 x 0.150 = 0.003375 cum. so concrete quantity for 1 cube = 0.003375 cum. concrete quantity for 12 cubes = 0.003375 x 12 = 0.0405 cum. We should take a little more quantity of concrete because it will stick on a trial mix drum and slump test purposes.
Get PriceOne of the purposes of the testing of concrete is to confirm that the concrete used in the structure has developed the required strength. As the hardening of concrete takes time, one will not come to know, the actual strength of concrete for some time. This is an inherent disadvantage in conventional test.
