Site adjustment method of concrete plant mixing ratio

Site adjustment method of concrete plant mixing ratio

Three hours before each opening, the concrete batching plant tester measured sand and gravel water content, and according to the theoretical basis of the construction mix than the conversion ratio, after the release of the person in charge of the mixing station. Test station should send a experienced test personnel responsible for the mixing station, and concrete slump degree, water volume, bleeding rate, detection of water binder ratio mixture performance index, when found to have as follows hou to mix adjusted as follows:

1, slump of the scene beyond with than design slump restrictions (+ 20mm), to timely analysis of the causes, rate of sand and gravel in water were determined. The coordination ratio correction, if moisture content measurement, calculation error is not, can will reduce the agent dosage increased or reduced by 0.05 ~ 0.1% adjustment.

2, when fresh concrete bleeding phenomenon, should be timely to identify the cause, if not admixture and cementitious material adaptability, can adjust the mixing ratio of the coarse aggregate, will adjust to the optimum gradation gradation, cut cannot apply fixed blending ratio.

3, when the sand ratio is too large or too small, should be identified in a timely manner, the sand ratio will be properly adjusted to adjust the ratio of 1%.

4, when more than 1 ~ 3 adjustment measures still can't solve the problem should be immediately stop plate, notify the mixing station and director of the center for lab director attended jointly analyze the causes, take timely and effective measures, so as to avoid the quality accidents.
