Aggregate how much influence on grouting material

Aggregate strength of grouting material also has certain influence, when stone strength equal than pebble gravel surface rough surface, it has to do with cement grout epoxy adhesive are better than pebbles, when the water cement ratio is equal or mixture phase at the same time, two kinds of material preparation of grouting materials, grouting material strength are better than pebbles. Varieties of fine aggregate strength of grouting material is smaller than the aggregate impact degree, so the formula of grouting material in sand do not reflect a soft effect, but the quality of sand quality of grouting material has a certain influence. Therefore, the sand quality must conform to the grouting material each label with sand quality standard requirements. Due to the construction site sand quality change is opposite bigger, so the site construction personnel must ensure that the sand quality requirements, and according to the on-site adjust water cement ratio, sand moisture content to ensure that the grouting material mixture ratio, ratio of proportioning and construction of the experiment don't mix.
