Abstract
The invention relates to a method for controlling the quality of a cement mortar floor. The method comprises the following steps that sand and cement are screened; the quality of the sand and the quality of the cement are strictly controlled, and the screened sand is washed; a base course surface is processed, specifically, constructing and painting landing ash, mud and sand on the base course surface are thoroughly removed, cement and concrete blocks protruding from the surface are chipped, and the base course surface is washed; wet processing is conducted on the base course surface, specifically, the base course surface is fully wet with clear water before plastering, and water accumulated in pits of a base course is wiped; mortar is prepared according to prescribed matching and is stirred uniformly; the cement mortar is subjected to screeding before initial setting, press polish is conducted before final setting, and finally brightness is pressed out with force; and natural drying is conducted, and after the floor is hardened for a certain period of time, timing watering maintenance is conducted on the floor continuously for several days. According to the method for controlling the quality of the cement mortar floor, gatekeeping is started from selection of raw materials, problems of all steps are prevented from occurring through an optimal mode, and problem occurring is avoided from the source.
Description
Technical field
A kind of the present invention relates to the realm of building construction, in particular it relates to method of control cement mortar surface quality.
Background technology
In industry with civil buildings, cement mortar surface is most widely used.By cement, bone flour and water, and the mortar that addition Calx, active blending material or additive are made at the scene as needed, it is divided into cement mortar and cement mixing mortar.In architectural engineering, one be basis and building wall, the binding agent as bulk material, such as build rubble, Rhizoma Begoniae Willsonii cement mortar；Two is that, for indoor exterior rendering, cement mortar adds stone just to become concrete by definite proportion row.
Cement mortar is in application process, if materials'use is improper, construction method is lack of standardization, be easy for causing cracking, dusting, decortication, the quality problems such as pitted skin and hollowing.
The content of the invention
The technical problem to be solved is to provide a kind of method of control cement mortar surface quality, to overcome existing cement mortar surface to cause the problem of the quality such as crackle, dusting, decortication, pitted skin and hollowing.
The present invention the adopted technical scheme that solves the above problems is：A kind of method of control cement mortar surface quality, comprises the following steps：
（1）The screening of sand, cement：Strict control sand, the quality of cement, and the sand after screening is rinsed；
（2）The process of substrate surface：Building by laying bricks or stones, painting landing ash and silt particle for substrate surface is thoroughly removed, and the cement on prominent surface and concrete block chisel are gone so that substrate surface is smooth, and substrate surface is rinsed, and is allowed to keep cleaning；
（3）The wettability treatment of substrate surface：Before plastering, abundant moistening is carried out to substrate surface with clear water, in order to avoid basic unit absorbs mortar moisture, and dry the hydrops of basic unit's pit, it is ensured that substrate surface was not only moist but also clean；
（4）Mortar is configured by the cooperation of regulation and is stirred；
（5）Cement mortar is carried out before pre-hardening floating, before final set, carry out press polish, final force extrusion light；
（6）Naturally dry, ground carries out watering maintenance through a period of time after-hardening, the timing of consecutive numbers day in cement mortar surface.
Cement mortar is in application process, if materials'use is improper, construction method is lack of standardization, be easy for causing cracking, dusting, decortication, the quality problems such as pitted skin and hollowing.The generation of crackle is as cement mortar is during solidification, part moisture and cement Jing Mr.'s chemical reaction colloids, another part moisture evaporation is fallen so that volume-diminished and cause ground contraction crack, conserve the generation for also resulting in crackle not in place in addition during final set；The out-of-flatness of basic unit, where projecting, screed is relatively thin, shrinks dehydration soon, and this is sentenced causes hollowing, and basic unit's differential settlement forms differential settlement, with the continuous increase of differential settlement, will crack or hollowing；Proportioning is unreasonable, stirs the excessive generation that may result in crackle of uneven and cement consumption；Using the unqualified generation for also resulting in crackle of raw material；During stirring mortar, water excess or stirring are uneven, surface press polish number of times is inadequate, the shaky appearance folding water of pressure, press polish poor timing, or press polish causes mortar top layer to be destroyed after final set, all it is the reason for causing dusting, water during Mortar shrinkage, drinking water differs and causes dusting at the excess moisture of part, the present invention starts to check on from the selection of raw material, it is analyzed for problem caused by each step meeting, the mode of optimization is taken to avoid the generation of each step problem, the generation of problem is avoided from source, so, instant invention overcomes existing cement mortar surface causes crackle, dusting, decortication, the problem of the quality such as pitted skin and hollowing.
Further, press polish point is carried out for 3 times.The problem for carrying out several times avoiding press polish uneven, improves press polish uniformity so that press polish is more solid, the problems such as can effectively avoid dusting, crackle.
Further, maintenance of sprinkling water is carried out continuously 10 days.It is best that the oxidation of 10 days enables to reaching for the quality on ground.
To sum up, the invention has the beneficial effects as follows：
1st, the present invention starts to check on from the selection of raw material, is analyzed for problem caused by each step meeting, takes the mode of optimization to avoid the generation of each step problem, avoid the generation of problem from source.
2nd, the present invention is carried out by press polish points for 3 times, carries out the problem that press polish can be avoided uneven several times, improves press polish uniformity so that press polish is more solid, the problems such as can effectively avoid dusting, crackle..
Specific embodiment
With reference to embodiment, make detailed description further, but embodiments of the present invention not limited to this to invention.
