Grouting and equipment foundation grouting material fluidity of how to test

Detecting grouting material fluidity grouting material is a common building materials, how about zhengzhou grouting material fluidity test? Below to listen to Li Yanglong to us in detail. 1, using planetary cement mortar mixer mixing, wipe with a damp cloth stirring pot and stir in advance leaf; 2, 1800 g cement grouting material is first poured into the pot, stir up, stir within 10 s l continue measuring good mixing water ( 12 recommended water ratio. 5%) , according to the mixing of cement mortar mixer fixed program end of the 240 s; 3, with a damp cloth to wipe glass plate in advance and truncated cone round mold wall, and the truncated cone dies placed in the center of the glass, then quickly filled grouting material mixture truncated cone round mould. Truncated cone dies for metal materials, inner surface should be smooth, for the next mouth diameter size to 100 + 0. 5 mm, flowing inside diameter 70 + 0. 5 mm, high 60 + 0. 5毫米; 4, glass plate size is not less than 500 mm x 500 mm and placed in a horizontal test-bed; 5, filed a truncated cone round slowly die, grouting material under the condition of without disturbance to the free flow and eventually stop, bottom diameter and maximum diffusion is measured with a caliper instead of the diameter of the vertical direction, calculate the average, as the fluidity of the initial value, the test result accurate to 1 mm, rounded up after expressed in mm and record data; 6, the fluidity of the initial value, stir from beginning to the end of the measuring time, should be completed within 5 min; Fluidity of 7, after the initial value measurement, quickly packed the glass grouting material into the pot, stir and use the wet cloth block mixing pot, prevent moisture evaporation; Fluidity of 8, after the initial value measuring 30 min, again will be stirring the pot grouting materials according to the fixed program mixer mixing 240 s, and then press A. 0. 1, 3, 4 terms, measuring the degree of value, as the fluidity 30 min retention value, and record the data.
