The Specific construction precaution of concrete of the present invention or building mortar surface reinforcing agent are as follows:
1, concrete surface toughener has extremely low surface tension, energy rapid osmotic is to inside concrete, with calcium hydroxide generation secondary reaction free after hydrated cementitious in concrete, generate a large amount of titanium dioxide hydrated calcium silicate gels, these gels can block inside concrete capillary micropore, thus the density of increase concrete surface, ultimate compression strength, hardness and wear resistance, generally can improve the 15-30% of concrete strength.In the concrete surface toughener of some two component and concrete, the reaction of related compounds is more complicated, it is a kind of organic with inorganic physical-chemical reaction, except generating hydrated calcium silicate gel, also can generate some and cause hard, fine and close material, make concrete intensity increase more obvious, namely the Cement Floor Dusting treatment agent of two component belongs to this kind of material, it can surface strength is poor, rise grey dusting cement concrete hardened ground to not dusting completely, do not play ash.Concrete surface toughener must be constructed at shaping sand-cement slurry or concrete surface:
2, in order to ensure that concrete surface toughener can infiltrate inside concrete more, suggestion new construction sand-cement slurry or concrete surface (preferably adopting machine to receive light) are constructed after wet curing at least 7 days, complete drying again.Certainly, after some concrete works builds 24 hours, i.e. application surface toughener, not only alternative curing agent, and the growth to concrete strength, meet design requirement, and reaches the effect of getting twice the result with half the effort.
3, the sand-cement slurry caused because of a variety of causes or concrete floor surface layer insufficient strength, grey dusting is played, concrete surface toughener can be used to carry out hardening, dust-proof process: its surface hardness of the ground after process and wear resistance obviously increase, do not play ash not dusting, the outward appearance of original ground is not changed.If repair the damage (as hole hole, crack etc.) of original ground, corresponding repairing technique must be taked to process.
4, the face seal of terrazzo floor or silicon carbide abrasion-resistant ground, enhancing: if coordinate machine polishing, polishing, the effect of similar marble floorings all can be made in these two kinds of ground.
5, the concrete product containing cement constituent or the surface enhanced of concrete member: the surface enhanced for concrete member it should be noted that, the green strength of concrete member is better, the amplitude that concrete surface toughener can promote is less, for the concrete of more than C30, concrete surface toughener is very little to its strength enhancing ability.
6, common constructional method uses low pressure spray, and (as atomizer), also can use round brush roller coating.Concrete surface toughener is evenly sprayed on basal plane, takes the method promotion infiltration of reciprocal spraying, brushing.When moisture evaporation, surface tacky is thick or when cannot see open fire, spray a small amount of clear water in time and keep moistening, whole time remaining about 4 hours, through natural curing, namely has obvious hardening effect after 24 hours.
If integral construction process coordinates, machine for renewing stone or brush ground machine are polished, polishing, and concrete surface toughener can be made to permeate more thorough, the luminance brightness of finished product concrete surface is better.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
