Abstract
The construction process of high strength macroporous permeating concrete road containing active mineral includes the following steps: mixing materials including stone, sand, water, cement, flyash, water reducing agent to form flowable cement mortar and concrete; molding the concrete via vibrating; demolding after 24 hr to obtain water permeating concrete paving material. The present invention solves the difficult problem of making water permeating concrete material possess high strength and long endurance.
Description
Technical field
The present invention relates to a kind of manufacture method that contains the high-strength macropore pervious concrete pavement of active mineral matter.
Background technology
How to reach on road surfaces such as highway, open car park, sidewalks make its have permeable, reduce noise, improve problems such as ride quality, be the problem that the many countries in the world today press for solution.At present, Chang Yong porous pavements material is divided into asphaltic base and cement based two big classes.The porous pavements material of asphaltic base is heat-resisting lacked with intensity difference, contaminated environment, life-span.The porous pavements material of cement based is compared with the porous pavements material of asphaltic base, advantages such as having permeable moist back stable performance, do not discharge harmful chemical in road environment, volume stability, durability are strong.But the intensity of the porous pavements material of cement based is low, and compressive strength is difficult to further raising in 15Mpa～25Mpa scope, thereby has hindered the applying of porous pavements material of cement based.Though the country that has adopts organic enhancing component as adopting vinyl acetate resin-ethylene copolymerization emulsions, polyvinyl formal, or the SBR rubber latex comes the intensity of the porous pavements material of refinforced cement base, but because the weatherability of organic enhancing component is poor, aging and be worth expensive easily.So add the high-strength and durable instructions for use that organic enhancing component still can not satisfy pervious concrete.Therefore, high-strength and durable instructions for use how to satisfy pervious concrete is a difficult problem that press for solution of pendulum in face of various countries scientist and researcher.
Summary of the invention
The purpose of this invention is to provide a kind of manufacture method that contains the high-strength macropore pervious concrete pavement of active mineral matter, this method can satisfy permeable, low-cost, the high-strength and durable instructions for use of porous of pervious concrete.
A kind of manufacture method that contains the high-strength macropore pervious concrete pavement of active mineral matter of the present invention is to be made of following steps:
(1) preparation of compound, the weight proportion of compound is:
Stone: sand: water=1: 0.1～0.3: 0.01～0.04
Above-mentioned compound is stirred in mixer, and 2～4 minutes time, described stone is a natural pebble, or its particle diameter of rubble is 5～40mm, and the fineness modulus of sand is 1.6～3.2;
(2) concrete preparation adds cement, active mineral admixture, water reducing agent in above-mentioned compound, the weight proportion of concrete preparation is:
Compound: cement: active mineral admixture: water=1: 0.1～0.4: 0.008～0.050: 0.02～0.08
Above-mentioned formulation is stirred, add water reducing agent again, make cement paste wherein produce flowability, stir again, 3～5 minutes time, obtain concrete mix;
(3) with in the above-mentioned concrete mix casting mold, moulding is smash in shake, and form removal after 24 hours obtains the pervious concrete paving brick, or above-mentioned concrete mix is cast in the subgrade construction, and roller-compaction obtains pervious concrete pavement;
(4) maintenance obtains the pervious concrete paving brick with above-mentioned, or pervious concrete pavement, in 15 ℃～25 ℃ of temperature, moisture-keeping maintaining, 7～15 days time.
Described water reducing agent can be choosing any one kind of them in naphthalene yarn water reducing agent, water-soluble resin yarn water reducing agent, lignin yarn water reducing agent, the molasses based water reducer, or several any combination.The addition of described water reducing agent is to account for cement to add 0.5～3% of weight.The optional NF of naphthalene yarn water reducing agent for example, the optional calcium lignosulfonate of lignin yarn water reducing agent, the optional ultraps sulfonic acid of water-soluble resin yarn water reducing agent are received etc.
Described active mineral admixture can be choosing any one kind of them in flyash, silica flour, water-granulated slag, volcano lime-ash, pozzolanic materials, the sintering soil, or several any combination.
Method of the present invention has following advantage:
1, the invention solves the difficult problem of the high-strength and durable instructions for use of pervious concrete.
2, have high strength, durable and permeable performance with the pervious concrete of the inventive method preparation, compressive strength reached 30～50Mpa in 28 days, and permeable yarn number reaches 1.0～10.0mm/s, and apparent density is 1900～2300kg/m
3The high strength of this permeable porous concrete is that the bonding by multiple inorganic material obtains, and does not contain any organic reinforcing, uses into low.
3, the present invention has simple advantage, is beneficial to the effect that makes full use of water resource, protection increase underground water, eliminates surface gathered water, the comfortableness that improves road traffic, safety, attenuating road traffic noise and protection environment simultaneously.
The specific embodiment
The weight proportion of compound is: stone: sand: water=1: 0.265: 0.020, stone are natural pebble, and its particle diameter is 5～25mm, and sand is river sand, and fineness modulus is 3.11, above-mentioned compound are stirred 3 minutes time in mixer.Add cement, flyash, water reducing agent again in above-mentioned compound, the weight proportion of concrete preparation is: compound: cement: flyash: water=1: 0.136: 0.024: 0.0313.Above-mentioned formulation is stirred, add the water reducing agent-calcium lignosulfonate that accounts for cement adding weight 2% again, make cement paste wherein produce flowability, thereby cement paste and formulation are stirred, 4 minutes time, obtain concrete mix; In above-mentioned concrete mix casting mold, moulding is smash in shake, and form removal after 24 hours obtains the pervious concrete paving brick, obtains the pervious concrete paving brick with above-mentioned, in 15 ℃～25 ℃ of temperature, moisture-keeping maintaining, 7 days time.Recording pervious concrete paving brick apparent density is 2259kg/m
