Description
One, technical field
The present invention relates to pavement engineering and job practicess thereof such as highway construction, especially stablize inflow formula polymer cement concrete pavement face structure and job practices in the class basic unit.
Two, background technology
1, cement concrete material and job practices thereof
Cement concrete material is a kind of widely known constructional materials, though concrete development has only the history in more than 100 year, nowadays become most widely used in the world wide, consumption is maximum, the constructional materials that almost is seen everywhere.Cement concrete with the cement slurry of inorganic material as adhesive material, bonding rubble and sand.The cement concrete of plastic state has certain fluidity, and closely knit for the inside concrete after guaranteeing to solidify, the general Vibration Technology that adopts is constructed during cast plastic state concrete, and cement paste solidifies the back and forms hard concrete as building stones.The characteristics that it has the convenience of drawing materials, construction is simple, intensity is high, can make arbitrary shape.Yet cement concrete material has himself unsurmountable weakness: the early solidification amount of contraction is big, the inner initial imperfection that easily produces; It is poor, easy to crack to adapt to deformability, and therefore people are devoted to the research of cement concrete modifying always for a long time.
In recent years, the appearance of polymer modified cement-concrete---concrete organising---makes this material of concrete go on a new developing stage again.Polymer modified cement-concrete is with polymer or polymer emulsion modified cement, and with polymer water mud or polymer emulsion modified cement paste as adhesive material, bonding rubble and sand.The resistance to compression of polymer modified cement-concrete, tension, impact strength all are improved largely, and have high erosion-resisting characteristics, and have the adaptable distinguishing feature of deformability, thereby have obtained using comparatively widely.
Polymer modified cement-concrete mainly as concrete repair material, ornament materials and house earth surface paver, also has fragmentary utilization in Structural Engineering, road surface and bridge floor at present.The construction technology of polymer modified cement-concrete has two kinds: 1. when wherein aggregate size is big, adopt and the identical technology of portland cement concrete construction: require polymer modified cement-concrete that bigger flowability is arranged, slump is generally at 3-5cm, cast back vibration compacting, general making thickness is 2-4cm; 2. the particle diameter that ought wherein gather materials hour requires polymer modified cement-concrete (being also referred to as polymer cement mortar) to have bigger flowability equally, adopts the mode that is similar to swabbing, and layering is brushed to the works surface, and general thickness is 0.5-2cm.Preceding a kind of form of construction work is used for the making of house earth surface, a kind of repairing, the decoration etc. of then being used in back.
In use there is following subject matter in existing polymer modified cement-concrete material: when adopting above-mentioned first kind of technology, because the contraction of polymer modified cement-concrete is general always greater than portland cement concrete, even best its amount of contraction of polymer modified cement-concrete of shrinkage is also only identical with ordinary concrete, therefore the shrinkage-compensating seam must be set during the polymer modified cement-concrete paving, can not continuous laying.When adopting second kind of construction technology, in order to guarantee that polymer modified cement-concrete does not ftracture, in the unit volume polymer modified cement-concrete amount of polymeric material big, involve great expense, in addition, the thickness that the technology of layering brushing once forms less (being not more than 1cm), therefore second kind of pavement of road (general all more than 4cm) laying that construction technology generally can not be used for large tracts of land and have certain thickness requirement.
2, the problem of Cun Zaiing
Conventional polymer cement concrete is that polymer, cement, rubble, sand etc. are mixed uniform mixing, the polymer cement concrete of formation, and then the work that paves, and what finally form is the polymer cement concrete of compact structure.Because therefore the polymer cement concrete properties of materials, a lot of problems can occur in the construction, is difficult to implement in engineering.This also just polymer cement concrete be difficult to the reason of large-scale promotion application in engineering.
