Abstract
The present invention belongs to the technical field of new material without nuisance for building, particularly to high performance soil coagulant. The high performance soil coagulant is characterized in that the high performance soil coagulant comprises the raw material of the following proportion by weight: 20 to 60% of cement clinker, 20 to 56% of slag, 8 to 24% of lime and 5 to 20% of gypsum. A technological process of the high performance soil coagulant comprises steps of raw material blending, ball milling and product inspection and package, or steps of ball milling, raw material blending and product inspection and package. The high performance soil coagulant does not need to be baked, and is produced at normal temperature and pressure; the present invention has the advantages of simple technology, wide purpose and low cost; the product performance of the high performance soil coagulant is better than that of the existing cement products; in use, sand and stone reinforced bar are not used, so manufacturing cost can be saved by 50 to 60%; the high performance soil coagulant has favorable alkali and acid corrosion resistance.
Description
The invention belongs to new material technology field for building, is a kind of nuisanceless high performance soil coagulant.It can be used for using on the various buildingss.As highway, railway, airport, water conservancy, harbour, dykes and dams, building etc.
The condensing agent that uses on the existing all kinds of buildings has cement, pitch.Cement and sandstone, reinforcing bar water mix just can become each base part for building.Pitch mainly contains stronger water resistance and is used for waterproof, adopt cement must make aggregate with sandstone as condensing agent for building, have certain limitation and cost higher, and its ultimate compression strength and folding strength and water leakage performance are also lower, the ability of opposing acid and alkali corrosion is also very poor.
The objective of the invention is to develop a kind of high performance soil coagulant for building of novel non-pollution.It is simple that it has technology, do not need roasting, normal temperature and pressure is produced down, and the product cost is low, and the ultimate compression strength and the folding strength of the soil buildings after condensing are significantly increased, the ability that stronger opposing acid and alkali corrosion is arranged, product is nontoxic, and the raw material of product has the blast-furnace slag waste material in the Iron and Steel Production, and waste material is turned waste into wealth, turn harm into good, then have ecological environment benefit preferably.
High performance soil coagulant of the present invention makes by following technological process.Its technological process is: proportioning raw materials is a cement clinker 20～60%, slag 20～56%, and lime 8～24%, gypsum 5～20%, aforementioned proportion are weight ratio: technological process has two: one, raw material blending → ball milling → examination and test of products packing; Two, ball milling → raw material blending → examination and test of products packing.The granularity of ball milling operation is controlled at 80um side's sieve, and screen over-size must not surpass 20%.Cement clinker is the cement products that the cement mill produces, and its label is high more, and then the performance of soil coagulant is good more, otherwise then performance is just poorer.Slag is the washing blast-furnace slag of discharging during Steel Plant produce, and this product is a solid waste, and it is turned waste into wealth, and good environment and economic benefit are arranged.Lime is the architectural lime of using always, and its major ingredient is a lime carbonate.Gypsum is the gypsum ore that Gypsum Mine is produced, and its major ingredient is a calcium sulfate, and the raw material blending operation is that raw material is cooperated the uniform process of remix by a certain percentage.The ball milling operation is with one raw material or with the plurality of raw materials that mixes ball mill finely disintegrated process.Examination and test of products packing is that multiple index such as the granularity, ultimate compression strength, folding strength to product is tested, and is packaged into the process of bag product after qualified again.For guaranteeing the optimum performance of its product, the optimum range of proportioning raw materials is a cement clinker 32～45%, and slag is 28～40%, lime 12～20%, and gypsum 10～15%, aforementioned proportion is weight percentage.This product appearance is that greyish white toner comes, and in use it can directly solidify various soil and mud at normal temperatures and pressures, and it is a kind of hydraulic glue gel material.During use, soil is about 70～90%, and soil coagulant is 10～30% then, is weight percentage, and poach tentatively solidified in about about 4 hours.Solidify fully and be about 12～24 hours.
Soil coagulant of the present invention has added raw materials such as cheap lime, gypsum, slag on the basis of cement clinker, without roasting, and normal temperature and pressure production, thereby technology is simple, the comprehensive Cheng Wei of product can reduce about about 40% than the cement cost.And the relevant salient features of this product is considerably beyond existing cement products, its ultimate compression strength is about 225～525MPa according to the formula for a product difference, folding strength then is 10～72MPa, be used for each main building foundation works in the use, need not use sand, stone, reinforcing bar just can meet or exceed existing sand, stone, the ultimate compression strength of reinforced concrete structure or folding strength, its cost can be saved 40～60% expenses, its intensity is higher in water environment, acid-alkali-corrosive-resisting is preferably arranged, broad prospect for its application is arranged, huge economy and society, environmental benefit are arranged.
Embodiment one: 400 kilograms of proportioning raw materials cement clinkers, and 300 kilograms in slag, 160 kilograms in lime, 140 kilograms in gypsum just can be produced 1000 kilograms of products with raw material blending → ball milling → examination and test of products technology of the package.
Embodiment two: 580 kilograms of proportioning raw materials cement clinkers, and 250 kilograms in slag, 90 kilograms in lime, 80 kilograms in gypsum just can be produced 1000 kilograms of products with ball milling → raw material blending → examination and test of products packaging process.
