Soon after arriving at the job web page, the concrete is completely blended. The drum is then turned for 70 to a hundred revolutions, or about five minutes, at mixing velocity.
Modifications in gradation also can affect workability with the concrete, While a wide array of gradation can be used for various apps.[seventy three][seventy four] An unwanted gradation can indicate utilizing a substantial aggregate that is definitely way too huge for the scale on the formwork, or that has much too number of smaller sized mixture grades to serve to fill the gaps concerning the bigger grades, or applying also little or an excessive amount sand for the same rationale, or making use of too minor h2o, or an excessive amount cement, or perhaps working with jagged crushed stone rather than smoother round combination which include pebbles. Any combination of บริษัทเอสเอชซี สหะชัยคอนกรีต จำกัด these variables and Other folks may possibly lead to a combination and that is much too harsh, i.e., which won't flow or spread out easily, is tough to get in the formwork, and and that is difficult to surface finish.[seventy five]
