Embodiment 1

[0022] A cleaning agent for cleaning exposed aggregate permeable concrete,

[0023] Its raw materials mainly include sodium gluconate and citric acid according to the mass ratio of 35%: 65% of the retarder 2%, industrial grade hydroxypropyl methylcellulose 0.05%, polyacrylamide 0.01% , iron oxide red 1%, fly ash 85%; the above raw materials are weighed by mass percentage, and added to the preparation vessel and stirred at a speed of 500rpm / min to form a uniformly dispersed mixture; when used, add The mixture is 100% water, and stirred for 1 minute to prepare the aggregate-exposed permeable concrete cleaning agent; immediately after the permeable concrete is poured, the cleaning agent is evenly and comprehensively sprayed on the surface of the permeable concrete, and then immediately covered with a film for curing, after 24 hours Rinse the concrete with a water gun to obtain permeable concrete with exposed aggregates; if the ambient temperature is low (below 25°C), the cleaning...

Embodiment 2

[0025] A cleaning agent for cleaning exposed aggregate permeable concrete,

[0026] Its raw materials mainly include sodium gluconate and citric acid according to the ratio of mass and number of 43%: 57% retarder 4%, industrial grade hydroxypropyl methylcellulose 0.15%, polyacrylamide 0.05% %, iron oxide red 3%, ordinary Portland cement 91%; the above raw materials are weighed according to mass percentage, and added to the preparation vessel and stirred at a speed of 500rpm / min to form a uniformly dispersed mixture; Add water with 150% of the weight of the mixture into the mixture, and stir for 1.5 minutes to prepare the aggregate-exposed permeable concrete cleaning agent; immediately after the permeable concrete is poured, spray the cleaning agent evenly and comprehensively on the surface of the permeable concrete, and then immediately cover the film for curing After 24 hours, rinse the concrete with a water gun to obtain permeable concrete with exposed aggregates; if the amb...

Embodiment 3

[0028] A cleaning agent for cleaning exposed aggregate permeable concrete,

[0029] Its raw materials mainly include sodium gluconate and citric acid according to the ratio of 50% by mass: 50%, 6% of retarder, 0.3% of industrial grade hydroxypropyl methylcellulose, and 0.1% of polyacrylamide , iron oxide red 5%, fly ash and ordinary Portland cement 98%; the above raw materials are weighed by mass percentage, and added to the preparation vessel and stirred at a speed of 500rpm / min to form a uniformly dispersed mixture; during use, Add water with 200% of the mass of the mixture to the obtained mixture, and stir for 2 minutes to prepare the aggregate-exposed permeable concrete cleaning agent; after the permeable concrete is poured, immediately spray the cleaning agent evenly and comprehensively on the surface of the pervious concrete, and then immediately Cover the film for curing, and rinse the concrete with a water gun after 24 hours to obtain permeable concrete with exposed ag...

Abstract

The invention relates to a cleaning agent for cleaning of pervious concrete with exposed aggregate, belonging to the field of surface cleaning of pervious concrete with exposed aggregate. The cleaningagent comprises the following main raw materials by mass: 2-6% of a retarder, 0.05-0.3% of a water retaining agent, 0.01-0.1% of a consistency regulator, 1 to 5% of a coloring agent and 85-98% of a filler. The cleaning agent of the invention is applicable in a wide environmental temperature range, low in spray amount fluctuation sensitivity, easy to color, easily controllable in penetration depthand long in controllable time, and can well realize surface aggregate exposure effect.

Description

technical field [0001] The invention relates to a cleaning agent for the surface of permeable concrete, which belongs to the technical field of cleaning the surface of permeable concrete with exposed aggregate. More specifically, the invention relates to a cleaning agent for cleaning the surface of permeable concrete with exposed aggregate. Background technique [0002] Permeable concrete is a kind of porous concrete with continuous pores made by mixing aggregates, cementitious materials, reinforcing agents and water, and has the characteristics of water permeability. [0003] Compared with ordinary permeable concrete, exposed aggregate permeable concrete adds a concrete surface treatment process. After the permeable concrete is formed, spray a layer of surface cleaning agent on the surface immediately to ensure that the slurry on the surface aggregate can be washed away after the concrete hardens for a certain period of time, so that the surface aggregate can reveal its ori...
