microsilica grout material depending on the type of building and underground the corrosion type, selection of acid or alkali resistance of orthopaedic/wow dioxide content is higher, the better the performance of the acid such as common granite, basalt stone and quartzite acid better stone, high content of calcium oxide and magnesium oxide dear see good performance, such as dolomite, limestone and marble, etc.
proper use of micronized grout
1. preparation before grouting
2. stirring of micro silicon powder grout: it shall be stirred according to the recommended proportion of the product before grouting. mechanical stirring and manual stirring can be adopted. the standard consistency is 13% to 15%.
3. determine the grouting method according to the actual situation: in general, the grouting method is self-weight grouting, that is, all kinds of silica powder grouting materials are poured directly from the entrance of the template, and the grout is poured and fixed in accordance with its own way after the grout enters. this is a general grouting method. if we encounter some special methods, we can use other methods for the environment, such as "high funnel grouting" or "pressure grouting".
4. maintenance system of microsilica grouting material: within 30 minutes after completion of grouting, curing agent should be sprayed or covered with plastic film and covered with rock quilt immediately, or wet and maintained immediately after final coagulation of grouting layer. (silica powder namely silica fume)
when microsilica is used in combination with efficient water reducing agent, the microsilica silica fume reacts with hydration products to form hydrated calcium silicate gel, fill the gap between cement particles, improve the interface structure and cohesive force, and form a dense structure. therefore, the strength of reinforced grouting can be improved significantly. ordinary microsilica content is 5%-10%. the super - high strength reinforced grouting material with compressive strength up to 100mpa can be prepared.
