Description
Technical field
The invention belongs to the field of building materials, propose a kind of pervious concrete special additive material composition.
Background technique
Pervious concrete is also known as celluar concrete, non-fine concrete, permeable terrace.Be by aggregate, cement, reinforcing agent and
A kind of porous light concrete made of water mixing, it is free of fine aggregate, mutual by coarse aggregate surface cladding a thin layer cement slurry
It bonds and forms the equally distributed honeycomb structure in hole, therefore have the characteristics that ventilative, permeable and light-weight.City is increased
Groundwater resources, alleviation tropical island effect, improvement urban climate have great importance.Pervious concrete requires enough strong
Degree and endurance quality, need to be adjusted by special additive, and mostly use normal concrete additional in Practical Project at present
Agent, easily causes that pervious concrete is dry, setting time is too fast, is not easy discharging, durability is poor, later strength is low, working performance is poor
The problems such as.
Summary of the invention
It is an object of the invention to improve the permeable breathable of pervious concrete, extend its setting time, propose a kind of saturating
Water coagulation soil special additive material composition.
Technical solution
For achieving the above object, the present invention provides following technical schemes:
A kind of pervious concrete special additive material composition, raw material includes: 30-40 parts of butyl methacrylate by weight,
10-20 parts of deionized water, 15-20 parts of ethylene glycol, partial size is no more than 5-10 parts of perlite powder of 20 mesh, and partial size is no more than 20 mesh
8-12 parts of calcium carbonate powder, 5-10 parts of trimethyl phosphoric acid of calcium carbonate amino, 3-5 parts of sodium citrate, 3-8 parts of waterglass, building
3-5 parts of gypsum, 1-3 parts of methyl anyl alcohol, 1-3 parts of rare earth.
Beneficial effect of the invention is:
1. improving the mobility of pervious concrete, premature drying, condensation are prevented.
2. concrete abrasion-resistant performance can be effectively improved while not reducing concrete strength.
3. permeable breathable is good, and rapid heat dissipation, urban heat land effect is effectively reduced.
