Description
Technical field
The utility model belongs to road engineering technical field, specifically, relates to a kind of porous cement concrete construction workability evaluating apparatus.
Background technology
Construction workability is a comprehensive technological property, has generally included three aspects such as mobility, water-retaining property and cohesiveness.Mobility refers to that fresh concrete is under deadweight or the machinery effect of vibrating, and can produce flowing, and even performance of filling up template densely.Mobility reflects the rare thick degree of mixture.If concrete mix is too dry thick, then poor fluidity, is difficult to vibration compacting; If mixture is excessively rare, then good fluidity, but easily there is laminated segregation phenomenon, major influence factors is the reinforcement of concrete water yield.Certain cohesive strength is had between the composition material that cohesiveness refers to fresh concrete, in work progress, the performance of unlikely generation layering and segregation phenomenon.The homogeneity of cohesiveness reflection concrete mix.If concrete mix cohesiveness is bad, then gathering materials in concrete is easily separated with grout, and cause concrete uneven, major influence factors is cement mortar rate.Water-retaining property refers to have certain water holding capacity at fresh concrete, in work progress, and the performance of the serious excreting water phenomenon of unlikely generation.The stability of water-retaining property reflection concrete mix.The inside concrete of poor water retention property easily forms water-permeable passage, affects concrete density, and reduces concrete intensity and permanance, and major influence factors is cement type, consumption and fineness.
The workability of fresh concrete is the comprehensive embodiment of mobility, cohesiveness and water-retaining property, the mobility of fresh concrete, both interknits between cohesiveness and water-retaining property, often there is contradiction again.Therefore, under the condition of certain construction technology, the workability of fresh concrete is the contradiction unification of above tripartite's surface properties.For fresh cement concrete, the evaluation method of its construction workability mainly contains slump method, ties up vigorous denseness method etc.And porous cement concrete due to its coarse fodder more, fines is less, uses slump method and ties up vigorous denseness method and can not better evaluate its construction workability.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of economical and practical, conveniently porous cement concrete construction workability evaluating apparatus.
A kind of porous cement concrete construction workability evaluating apparatus described in the utility model, described porous cement concrete construction workability evaluating apparatus comprises storage bin 1 and shell 7; Described storage bin 1 is for loading porous cement concrete 2, and its two bottom sides is an external collection stock tank 3 respectively; Described collection stock tank 3 is communicated with by the grout outlet 4 on the bottom side edge of storage bin 1, and the bottom of this collection stock tank 3 is provided with slurry discharging hole 5; Described shell 7 is located at the below of storage bin 1, is provided with the motor 6 be connected with electronic scales 14 in it, is also provided with power switch 8, electronic scales control knob 9 and motor switch 10; Described electronic scales 14 is by wiring 12 connection data processor 13 and display 11 successively.
A kind of porous cement concrete construction workability evaluating apparatus described in the utility model, the precision of described electronic scales 14 is per mille gram.
A kind of porous cement concrete construction workability evaluating apparatus described in the utility model, described storage bin 1, collection stock tank 3 and shell 7 are made by stainless steel.
During operation, porous cement concrete construction workability evaluating apparatus described in the utility model is by applying centrifugal force certain hour to newly mixing porous cement concrete, making to stick to superfluous water mud on gathering materials with gathering materials is separated, then the quality of superfluous water mud is tested, draw superfluous water mud and initial concrete quality ratio, evaluate its construction workability by the size of ratio.
Compared with prior art, porous cement concrete construction workability evaluating apparatus described in the utility model is for newly mixing porous cement concrete, by collecting the grout quality that stock tank is collected in test certain hour, obtain grout quality concrete gross mass ratio front with test, evaluate the construction workability of newly mixing porous cement concrete with this.It compensate for the deficiency that porous cement concrete construction workability evaluates field, and test philosophy is simple, easy and simple to handle, economical and practical.
