Abstract
The invention discloses a chlorine oxygen magnesium cement stable macadam pavement base material which is composed of the following components in percentage by weight: 1-3% of lightly fired powder, 1-4% of lightly fired dolomite powder, 0.1-0.5% of silica fume, 0.01-0.05% of phosphoric acid, 0.5-2% of industrial magnesium chloride, 85-92% of aggregate and the balance of water. The chlorine oxygen magnesium cement stable macadam pavement base material has long setting time which is sufficient for construction time, and has excellent early strength; the 3d unconfined compressive strength is up to 4 MPa above; the properties are better than those of the traditional Portland cement stable pavement base material; and the chlorine oxygen magnesium cement stable macadam pavement base material is especially suitable for arid cold area in western China, and has obvious economic and broad market prospects.
Description
Technical field
The present invention relates to building material field, be specially a kind of magnesia oxychloride cement stable gravel roadbase material.
Background technology
Cement stabilized macadam, is called for short water steady, is with cement, rubble for raw material, carries out mix, pave, roll the roadbase structure of formation with suitable grating and proportioning.Because this kind of structural sheet still belongs to semi-rigid material, compare double-lime litho basic unit conventional in urban infrastructure road engineering, there is the advantage that early strength is high, quality stability good, integral rigidity is large, but there is the feature of ability of anti-deformation difference, easily the generation temperature difference and desciccation crack simultaneously.Along with the quickening of our urbanization process, many municipal infrastructure projects are after extensive extensive property construction in early stage, expose a lot of problem gradually, as road cracking, sink, inspection shaft and cross pipe backfill sink etc., especially the quality Control of double-lime litho sub-surface in road engineering, there is quality of materials and be difficult to ensure that card is (due to environmental requirement, the flyash sulphur content residual as power plant is most higher), construction technology falls behind, these have all had a strong impact on the integrated engineering quality of road and traditional portland stablizes road surface base layer material, time of coagulation is shorter, require higher to the engineering time, its early strength is also poor simultaneously, be not suitable for the western arid and cold region of China especially.
Summary of the invention
The object of the present invention is to provide a kind of magnesia oxychloride cement stable gravel roadbase material, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of magnesia oxychloride cement stable gravel roadbase material, composed of the following components by weight percentage:
As the further scheme of the present invention, content of magnesia>=80% of described light burnt powder, activated magnesia>=60%, calcium oxide≤2%, loss on ignition≤8%, specific surface area>=350m
2/ kg.
As the further scheme of the present invention, content of magnesia>=25% of described light dolomite powder, dioxide-containing silica≤3%, specific surface area>=350m
2/ kg.
As the further scheme of the present invention, dioxide-containing silica>=85% of described silicon ash, specific surface area>=15000m
2/ kg.
As the further scheme of the present invention, the H of described phosphoric acid
3pO
4content>=85%.
Compared with prior art, advantage of the present invention: this magnesia oxychloride cement stable gravel roadbase material, time of coagulation is longer can enough engineering times, there is excellent early strength simultaneously, 3d unconfined compression strength reaches more than 4MPa, performance is better than traditional portland and stablizes road surface base layer material, is specially adapted to the western arid and cold region of China, has significant economic and wide market outlook.
