Description
Technical field
The utility model relates to a kind of sand-cement slurry length stabilisation checkout equipment.This equipment can obtain the self-constriction data of sand-cement slurry.
Background technology
Sand-cement slurry by the potpourri of cement, sand and water sand-cement slurry.For places such as construction works, as built a house.Due to the Early self-shrinkage problem caused as cement self hydrated properties of sand-cement slurry major gelled material, bring many obstacles to sand-cement slurry application in practice.Self-constriction refers to that cement slurry is under the condition of outwardly not dewatering, because inner hydrated cementitious proceeds, in pore, free water amount is not enough, makes the spontaneous minimizing of slurry internal relative humidity, cause internal capillary tension force to increase and form internal stress, the slurry drawdown deformation of generation.Self-constriction mainly occurs in cement setting hardened early, and now hydrated cementitious proceeds, and self-constriction causes slurry volume to reduce, but cement paste structure oneself there is certain intensity, make cement paste structure inside formed stress, finally cause structure crack.Especially high efficiency water reducing agent is since construction industry widespread adoption, and water-cement ratio significantly declines, the problem of Cracking that self-constriction causes more serious.
Mortar shrinkage determinator in national standard is only applicable to the drawdown deformation after detecting test specimen sclerosis, cannot measure the self-constriction distortion of mortar early-age plastic stage generation.The principle of work of the experimental provision of current existing mensuration mortar early-age plastic stage self-constriction is roughly divided into volumetric method principle and length, height method principle two class: volumetric method directly measures the external volume of slurry, is weighed the self-constriction size of slurry by the change of external volume; Length, height method calculate the size of self-constriction change by the measurement change of cement slurry volume being changed into length or height.Volumetric method is directly perceived and variable is less, but method implements comparatively difficulty; Length, height method are that volume change is converted into length or height change, have the advantage that simple to operate, result is easy to get.
Wherein, sand-cement slurry length detection equipment, adopts hand dipping to there is the phenomenon of test specimen carrying, and test specimen, when maintenance and measurement environment can not get both, is measured test specimen existence and is moved out of the situations such as measuring gage fixed ring border.Data difference is large and reductibility is poor, departs from and can only reform once there is larger data, wasting manpower and material resources.Apparatus measures equipment Inspection is exactly vertical survey with horizontal survey simultaneously, and the tight ness rating of test specimen and support is poor with laminating degree, and cost of equipment is expensive simultaneously, almost can not scale test.Architecture engineering material is that every other commodity are incomparable in quantity and weight sum, so the economic loss that minimizing manual operation error is brought is huge.
