Abstract
The invention discloses a high-strength plant growing type porous concrete and a preparation method thereof. The concrete comprises the following ingredients in proportioning by weight: water, cement, waste concrete or natural crushed stone aggregate, water reducing agents and rice straw. The preparation method comprises the steps of: firstly crushing the waste concrete or the natural crushed stone aggregate to be used as aggregate for later use; smashing the fully dried rice straw for later use; stirring the aggregate and a proper amount of water for a period of time; putting a proper amount of cement, the smashed rice straw and the water reducing agents into a stirrer for stirring; and finally, adding rest water and cement to be stirred. The high-strength plant growing type porous concrete can replace masonry flagstone with the strength of lower than M15, is applied to engineering projects such as raceways, parking lots, side slopes, riverbanks and the like and helps the growth of plants and restores the ecological environment destroyed by construction under the application condition.
Description
Technical field
The present invention relates to the environment-friendly building materials field, particularly, relate to a kind of high strength vegetation form cellular concrete and preparation method thereof.
Background technology
At reservoir, rivers and creeks embankment, the place that road slope and massif bank protection etc. must harden and reinforce because of requirement of engineering, cellular concrete is because of itself and the similar engineering of normal concrete, replaces normal concrete gradually and becomes at first construction material but have plant growth property that normal concrete do not possess and restoration of the ecosystem.Common cellular concrete because the reason of its mix material proportioning and stirring technique exist intensity on the low side (though or reach requirement of strength, but member thickness is big, be difficult to transportation and construction), porosity is little, water-permeable reduction in time, poor durability and internal pH-values are too high can not be beneficial to shortcoming such as plant-growth, limits it and uses in the region that some high strength are had relatively high expectations, the temperature difference is big, precipitation is more.Therefore need improve the cellular concrete technology of having used at present both at home and abroad, to overcome above shortcoming, so that the advantage of planting natural disposition and restoration of the ecosystem of cellular concrete obtains the use of maximum range.
Summary of the invention
The objective of the invention is to propose a kind of high strength vegetation form cellular concrete, can substitute the mortar flag stone that intensity is lower than M15 and be used in greening and the restoration of the ecosystem satisfied under the requirement of engineering situation at above-mentioned defective of the prior art.
Another object of the present invention provides a kind of preparation method of high strength vegetation form cellular concrete.
The technical scheme that realizes above-mentioned purpose is as follows:
A kind of high strength vegetation form cellular concrete, comprise water, cement, discarded concrete or natural rubble aggregate, water reducer and rice straw, the weight proportion of each compound is as follows: the water cement ratio (ratio of water and cement, weight ratio) is 1: 3, the ratio of discarded concrete or natural rubble aggregate and cement is 10: 1, the consumption of water reducer is 1% of a cement consumption, and the ratio of rice straw and discarded concrete or natural rubble aggregate is 1000: 3.
Further, described cement is No. 525 cement.
Further, described discarded concrete or natural rubble aggregate are the aggregate of single particle size 4cm.
Further, described rice straw length is 2.8～3.2cm.
Further, described water reducer is a high performance water reducing agent of polyocarboxy acid.
The preparation method of a kind of high strength vegetation form cellular concrete of the present invention comprises the steps:
(1) preparation of raw material
With the discarded concrete or the natural rubble crushing of collecting, get particle diameter after sieving and be 4cm for aggregate standby; With the rice straw fragmentation of thorough drying, choosing length is the standby of 2.8～3.2cm;
By water cement ratio is 1: 3, and the ratio of discarded concrete or natural rubble aggregate and cement is 10: 1, and the consumption of water reducer is 1% of a cement consumption, and the ratio of rice straw and discarded concrete or natural rubble aggregate is 1000: 3, and said ratio is weight proportion;
(2) stir
The aggregate that step (1) is made adds 70% of the described raw material water yield and stirs earlier, and churning time is 1 minute; Subsequently with the raw material cement amount 50%, all water reducer and all rice straw join in the stirrer and stirred 1 minute; At last remaining whole cement and water are added in the stirrer, stirred 2.5 minutes.
Further, described cement is No. 525 cement.
Further, described water reducer is a high performance water reducing agent of polyocarboxy acid.
The present invention compares with traditional cellular concrete following two outstanding characteristics:
The one, the use of super large single particle size aggregate, particle diameter is that rubble or the discarded concrete aggregate of 4cm is the ultimate compression strength that has guaranteed cellular concrete; And be the reason of high porosity.
The 2nd, add through thorough drying and be broken into the rice straw that length is 3cm.The benefit of adding rice straw has: rice straw can be used as microorganism carrier, and the microorganism that is added on like this in the nutrition soil will have suitable organic environment to adhere to and the performance function; As time goes on, adding soil and can be compacted and be unfavorable for plant-growth in the tradition cellular concrete, and atmospheric disintegration of rocks thing or other material also may add original hole completely, the voidage of so traditional cellular concrete reduces and loses its plant-growth performance, but the present invention just this phenomenon can not occur because add rice straw, and As time goes on, rice straw can be corrupt as organism, thereby Free up Memory, delayed the time that voidage diminishes.The effect of adding fiber in the bituminous concrete has been played in the interpolation of rice straw, strengthened the contact between the aggregate, and rice straw has certain toughness, even the cement after solidifying is because climate change has trickle crack also can guarantee the integrity of cellular concrete, thereby weather resistance and freeze-thaw resistance are improved.
Promptly compared with prior art, the invention provides a kind of new cellular concrete mix material proportioning and stirring technique thereof, it is on the low side to have solved present traditional cellular concrete intensity, porosity is little, water-permeable reduction in time, poor durability and the too high shortcoming that can not be beneficial to plant-growth of internal pH-values, thereby make the scope of application of cellular concrete wider, better promotion plant-growth ability and restoration of the ecosystem ability are arranged.Can substitute the mortar flag stone that intensity is lower than M15 is used in greening and the restoration of the ecosystem satisfied under the requirement of engineering situation.
