Description
Technical field
The present invention relates to a kind of early strong waterproofing agent, particularly a kind of morning for Portland cement is strongWaterproofing agent.
Background technology
Concrete early strength agent is one of additive kind using the earliest in additive developing history. Up till nowTill, people are the multiple early-strength additive of exploitation except villaumite and sulfate successively, as nitrous acidSalt, chromate etc.; And organic matter early strength agent, as triethanolamine, calcium formate, urea etc. AndOn the basis of early strength agent, the multiple composite additive of production application, as early strength water-reducing agent, early strength antifreezing agentWith early-strength pumping admixture etc. Although early strength agent produce and applicating history longer, along with people to chlorion,Sulfate ion, nitrate ion and alkali metal ion etc. are to concrete performance and the potential danger of long-time stabilityThe intensification of the awareness of evil, and the exploitation of large slag powder or flyash concrete, at early strength agentAspect also needs to do a large amount of work. Early strength agent Main Function is the reaction speed that increases cement and water, shortensThe condensing of cement, firm time, promote the growth of early age strength of concrete. Waterproofing agent can improve coagulationThe anti-permeability performance of soil, reduces concrete quality water suction dose rate, and durability also obviously improves. Existing skillThe composition of strong waterproofing agent morning because adding in art, though can strengthen the early effect of strong waterproofing agent, still the while alsoHuman body is damaged or environment. And endeavour now to study, one is little to human injury, ringGuarantor, green, efficient early strength agent waterproofing agent, have morning by force and the engineering of waterproof requirement thereby meet.
The information that is disclosed in this background technology part is only intended to increase the reason to general background of the present inventionSeparate, and should not be regarded as admitting or imply that in any form this information structure has been this area general technologyThe prior art that personnel are known.
