Abstract
The present invention discloses a cement-based composite material with environmental protection, which comprise active components, fine aggregating materials, water and a superplasticizer, wherein the active components comprise 1 portion of cement and 0.2 to 1.5 portions of pulverized coal ash according to proportion by weight. The active components can comprise1 portion of cement, 0.2 to 1.3 portions of pulverized coal ash and 0.05 to 0.2 portion of silica ash according to proportion by weight, and can also comprise 1 portion of cement, 0.2 to 0.8 portion of mineral powder and 0.2 to 0.8 portion of pulverized coal ash according to proportion by weight. Because the mineral powder and the pulverized coal ash which are industrial waste residues are used as raw materials, the cement-based composite material has the advantages of environmental protection, cost reduction and high compressive resistance.
Description
(1) technical field: the present invention relates to a kind of material of construction, especially a kind of environment protecting cement-base composite material.
(2) technical background: the super high strength concrete that reaches 150-200MPa for ultimate compression strength, be starting material with cement, silicon ash, sand, ultrafine quartz powder, superplasticizer, water, fine steel fiber in the world, by hot water maintenance or high-temperature pressurizing maintenance, prepare ultimate compression strength and reached 170-230MPa, bending strength reaches the very-high performance RPC of 30-60MPa, but this material exists the manufacturing cost height, is not suitable for the defective that China produces.The reason that this defective produces is: 1. used raw material silicon ash volume height (more than 25%) in the prior art, and the silicon of China ash output is very low, price height (being higher than 2500 yuan/ton) is difficult to realize that the large-scale popularization of RPC uses.In addition, the silicon ash is light especially because of it, transportation inconvenience.2. the levigate silica powder consumption of used starting material big (more than 30%) in the prior art, energy consumption is big, price is high.
(3) summary of the invention:
Technical problem the present invention is directed to the high defective of material cost in the prior art, proposes the environment protecting cement-base composite material that a kind of cost is low and performance is fair.
A kind of environment protecting cement-base composite material of technical scheme comprises: active constituent, fine aggregate, water and superplasticizer, active constituent comprises: cement and flyash, its proportioning (weight ratio) is: cement: flyash=1: (0.2-0.5).
Beneficial effect is 1. because the present invention has utilized flyash, breeze as its raw material, consumed the existing industrial residue that is unfavorable for environmental protection, both reduced cost, help environmental protection again, in addition, the present invention has the high advantage of ultimate compression strength, its ultimate compression strength is higher than 100 MPas, even be higher than 120 MPas, so the present invention is the environment protecting cement-base composite material that a kind of performance is fair and cost is low.2. the adding of silicon ash has further improved ultimate compression strength, make its ultimate compression strength be not less than 150 MPas, though the adding of silicon ash has slightly improved cost, but because the add-on of silicon ash is lower than the add-on of prior art, so, the technical measures that add the silicon ash had both improved ultimate compression strength, had kept the cheap relatively advantage of cost again.3. fortifying fibre can improve more than the ultimate compression strength 10%-30%, and bending strength improves more than 2-4 times, and energy-to-break improves more than 50 times.4. comprise the technical scheme of components such as breeze, cement, flyash, silicon ash, fortifying fibre, can make ultimate compression strength of the present invention reach 160-250MPa, bending strength reaches 30-60MPa.5. fine aggregate adopts natural fine sand to help further reducing cost, and not only can make the present invention with low cost by the fine aggregate that natural fine sand and levigate silica powder are formed, and can improve ultimate compression strength of the present invention.
(4) embodiment: the present invention is a kind of environment protecting cement-base composite material, comprise: active constituent, fine aggregate, water and superplasticizer, active constituent comprises: cement and flyash, its proportioning (weight ratio) is: cement: flyash=1: (0.2-1.5), can select for use 1: 0.2, also can select for use 1: 1.5, can also select 1: 0.5 or 1: 1.1 etc. for use, active constituent of the present invention also comprises the silicon ash, cement, the proportioning of flyash and silicon ash (weight ratio) is: cement: flyash: silicon ash=1: (0.2-1.3): (0.05-0.2), can select for use 1: 0.2: 0.05, also can select for use 1: 1.3: 0.2, can also select for use 1: 1: 0.06,1: 0.4: 0.17 or 1: 0.7: 0.12, active constituent of the present invention also comprises breeze, cement, the proportioning of breeze and flyash (weight ratio) is: cement: breeze: flyash=1: (0.2-0.8): (0.2-0.8), for example: its proportioning (weight ratio) can be selected for use 1: 0.2: 0.2, also can select for use 1: 0.8: 0.8, can also select for use 1: 0.3: 0.7,1: 0.7: 0.4 or 1: 0.4: 0.4, in the present embodiment, the present invention includes fortifying fibre, the fortifying fibre volume that is added is the 1%-3% of the mixed back of all the other components cumulative volume, above-mentioned fine aggregate is that natural fine sand or above-mentioned fine aggregate are made up of natural fine sand and levigate silica powder, and levigate silica powder normally particle diameter is not more than 0.1 millimeter silica powder.The proportioning of active constituent and fine aggregate, water, superplasticizer (weight ratio) is 1: (1-1.4): (0.14-0.25): (0.01-0.02).Manufacturing process of the present invention is as follows: (1) active constituent is stirred (if superplasticizer adopts pulvis, then stirring simultaneously with active constituent); (2) fine aggregate is added in the active constituent stir; (3) fortifying fibre is scattered in the above-mentioned mixed material, makes fiber dispersion even; (4) water (if superplasticizer adopts aqua, then adding simultaneously with water) is added in the mixed material of front, stir; (5) with above-mentioned mixed material dress mould, vibratory compaction, curing in the mold demoulding after 24 hours; (6) test specimen after the demoulding was carried out 60-90 ℃ of hot water maintenance 1-3 days or through the hot water maintenance after 1-3 days again through 160-300 ℃ of high temperature steam press maintenance 6-12 hour, or some days of maintenance in the environment of preserving moisture naturally.
