Problems solved by technology

[0003] However, the existing permeable concrete test block production process is relatively cumbersome, which increases the difficulty of the work, and the raw material ratio of the permeable concrete test block is not uniform, and the ingredients are not fully mixed, so that the use of the permeable concrete test block produced The effect is not good, and the water permeability of the permeable concrete test block is reduced, thereby reducing the use rate, and the production time is relatively slow during the production process, thereby reducing work efficiency

Embodiment 1

[0032] As a preferred embodiment of the present invention, according to step 2, the adjustment steps of the construction mix ratio are as follows: firstly, the mix ratio of the laboratory is set as: cement: water: sand: gravel=1: x: y: z, and the moisture content of the sand on site is m, the water content of stones is n, then the construction mix ratio is adjusted to: 1: (x-y*m-z*n): y*(1+m): z*(1+n).

[0033] This kind of permeable concrete test block production method calculates the moisture content of sand and the moisture content of stones through the calculation method of 1: (x-y*m-z*n): y*(1+m): z*(1+n), so that The manufacturing method of the permeable concrete test block is more specific, the error is reduced, and the mixing ratio is more accurate.

Embodiment 2

[0035] As a preferred embodiment of the present invention, according to step 5, the vibrating table vibrates the trial mold while the mixture B is loaded into the trial mold, and the trial mold shakes slightly during the vibration process, according to step 8 , the ambient temperature of test block C is controlled at 25°C, and the curing of test block D needs to be cured at 25°C.

[0036] This permeable concrete test block production method is to successively load the mixture B into the test mold during the vibration process, so that the vibration effect of the mixture B in the test mold is better, and the vibration of the mixture B is more uniform. Thereby improving work efficiency and reducing work difficulty.

Embodiment 3

[0038] As a preferred embodiment of the present invention, according to step 2, each component material of concrete is allowed to have a certain deviation, for example: water or cement≤±0.5%, coarse or fine aggregate≤±1%, admixture or admixture ≤±0.5%, according to step 7, when the test block B is close to initial setting, use a spatula to smooth the surface of the test block B.

[0039] This kind of permeable concrete test block manufacturing method makes the deviation of this kind of permeable concrete test block manufacturing method smaller by setting the deviation value, so that the use effect of the concrete test block is better, and the surface of the test block B is wiped with a spatula Flat, so that the aesthetic effect of this kind of test block B is better.

Abstract

The invention discloses a pervious concrete test block manufacturing method. An existing pervious concrete test block manufacturing technology is complex, the work difficulty is enlarged, matching ofraw materials of a pervious concrete test block is uneven, consequently, the usage effect of the manufactured pervious concrete test block is not good, water permeability of the pervious concrete testblock is reduced, the usage rate is reduced, the manufacturing time is long in the manufacturing process, and consequently the work efficiency is reduced. According to the pervious concrete test block manufacturing method, the concrete raw materials are mixed according to a certain proportion, then, a stirring machine is used for conducting stirring, the pervious concrete test block manufacturingtechnology is simpler, and the work difficulty is lowered. The stirring machine is used for driving stirring blades to stir the concrete raw materials, mixing of the concrete raw materials is more uniform, calculation is conducted through the actual formula, accordingly, matching of the pervious concrete test block raw materials is more uniform, and accordingly the usage effect of the manufactured pervious concrete test block is better.

Description

technical field [0001] The invention relates to the technical field of concrete test blocks, in particular to a method for manufacturing a permeable concrete test block. Background technique [0002] Ecological permeable concrete is a mixed material composed of cement, water, permeable concrete reinforcing agent (cementing material) mixed with high-quality aggregates of the same particle size or discontinuous gradation, and has a certain porosity. [0003] However, the existing permeable concrete test block manufacturing process is relatively cumbersome, which increases the difficulty of the work, and the raw material ratio of the permeable concrete test block is uneven, and the ingredients are not fully mixed, so that the use of the produced permeable concrete test block The effect is not good, and the water permeability of the permeable concrete test block is reduced, thereby reducing the use rate, and the production time is relatively slow during the production process, t...
