Abstract
The invention discloses a device for measuring slump and actual loss of concrete. The device can simulate the actual transportation state of concrete and has the advantages of reducing construction cost and ensuring the working performance of concrete. The device is provided with a fixed frame (1) and a rotating shaft (6), wherein the fixed frame (1) are fixedly connected with two axial sides of a cylindrical body (3) through a bearing (2), the cylindrical body (3) is provided with a material inlet (4) and a material outlet (5), the end of the rotating shaft (6), which is outside the cylindrical body (3), is connected with power equipment, and the end of the rotating shaft (6), which is inside the cylindrical body (3), is fixed to a stirring blade (7).
Description
Technical field
The present invention relates to concrete construction work performance evaluation technical field; Especially a kind of can simulation concrete actual shipment state; Construction costs can be reduced, the device that is used to measure concrete slump actual loss amount of workability of concrete ability can be guaranteed simultaneously again.
Background technology
Therefore at present, in field of civil engineering, commerical ready-mixed concrete all adopts pumping construction, just requires concrete must have certain fluidity, its mobile size usually with the slump as measurement index.Because concrete is through transportation; Its slump can reduce (being referred to as slump-loss); So the initial slump of concrete that transports from concrete mixing plant must be construction reference value and slump-loss value sum, could guarantee the serviceability of cast on-site concrete.The method that the existing concrete slump-loss is measured is: get part mixed concrete just, with slump cone its slump is measured, income value is the initial slump; Remaining part places airtight container; Leave standstill the some time (concrete delivery truck carries out pumping operation from mixing plant to working-yard haulage time); Carry out the slump with slump cone again and measure, the difference of the income value and the initial slump is the slump-loss of corresponding time.Yet; In the actual engineering; Commerical ready-mixed concrete is in transportation in the uniform rotation of tank body all the time, and uniform rotation can slow down concrete coagulation, is statically placed in the concrete in the container with respect to existing measuring method; Its slump-loss is less, has error between slump-loss that promptly existing method is surveyed and the actual loss amount.Because error exists, and makes the initial slump of concrete bigger than normal, has both wasted concrete additive, has increased concrete cost, also can cause concrete component early crack to occur simultaneously, makes the reduction of component durability property.
Summary of the invention
The present invention is in order to solve the above-mentioned technical matters of existing in prior technology; Provide a kind of can simulation concrete actual shipment state, can reduce construction costs, can guarantee again simultaneously workability of concrete can the device that is used to measure concrete slump actual loss amount.
Technical solution of the present invention is: a kind of device that is used to measure concrete slump actual loss amount, be provided with fixed mount, and fixed mount is fixedly connected to both sides through bearing and drum shaft, and charging aperture and discharging opening are arranged on the said cylindrical shell; Be provided with the rotating shaft of passing bearing, be positioned at cylindrical shell outer rotating shaft one end and power-equipment and join, be positioned in the rotating shaft of cylindrical shell and be fixed with agitation blades.
Said power-equipment comprises motor, reducer casing, driving wheel, driving-belt that is arranged on the fixed mount bottom and the engaged wheel that is fixed on rotating shaft one end.
Said charging aperture is arranged on the radial side of cylindrical shell, and said discharging opening is arranged on the axial end of cylindrical shell.
Said agitation blades is at least three rows, in cylindrical shell axially on the left, center, right be uniformly distributed with and inclination and rotating shaft.
The present invention is when measuring concrete slump loss; Can simulation concrete actual shipment state, can accurately measure the concrete slump actual loss, solved existing measuring method existing with the inconsistent problem that causes error of practical engineering application; Can reduce the initial slump of concrete relatively; Avoid both can reducing construction costs, can guarantee the workability of concrete ability again simultaneously because of the excessive defective that exists of the initial slump value of concrete.
