Time and temperature on the influence of epoxy grouting material workability - Fuzhou epoxy grouting material manufacturers

Epoxy grouting epoxy grouting material manufacturer epoxy grouting material price building materials test new mix epoxy grouting material has thickened gradually with time. This should not confused with the condensation of epoxy grouting material. Part of the reason is very simple, the mixture of water absorbed by aggregate, part of transpiration, especially epoxy grouting material in the sun or wind conditions more simple transpiration, some initial chemical reactions involved in the water. From a batch after an hour, dense factor down about 0. 1. Job loss accurate value depends on several factors. First of all, the higher the initial operation sex, the greater the slump loss. Second, the rich mixture, slump loss rate is higher. And lost speed depends on the nature of cement used, high alkali content and sulphate content is very low, high loss rate. Building materials through the test of epoxy grouting material wet sieve slurry ( Use the mm sieve) , to determine whether the epoxy grouting material. With a spring reaction probe ( Called the proctor probe) Test of penetration resistance is 3. 5 mpa and 27. 6 mpa. The former is the initial setting time, appearance epoxy grouting material has yinchuan epoxy grouting material wholesale cohesion, so that vibration also cannot make its flow. Penetration resistance to 27. 6 mpa moment is the final setting time; The compressive strength at this time of the test with a standard cone is about 0. 7MPa。 The coagulation time and cement coagulation time is different. Homework mixture sex are also affected by environmental temperature, but strictly speaking, we care is the temperature of the epoxy grouting material itself. Because homework decreases with time, that is to say, the determination of mixing after the completion of a very important moment in the slump, in order to control ingredients, pour in the epoxy grouting material from the mixer without shrinkage after the epoxy grouting material composition should be the test of the slump is useful. Methods for dense used to ensure that operation is appropriate, when epoxy grouting material pouring into the mould immediately the slump test is also useful. Homework sex change with time are determined by the water content of the aggregate ( In total water use a punctual) : because aggregate absorb moisture, use dry aggregate epoxy grouting material loss is bigger, this is the same as expected. Water reducing the seam an agent will usually cause slump loss rate has increased over time, although they can postpone the initial setting time of epoxy grouting material.
