Technical field
The present invention relates to concrete fields.
Background technology
Grouting material be using high-strength material as aggregate, using cement as bonding agent, be aided with upper flow regime, microdilatancy, prevent from
The substances such as analysis are formulated.A certain amount of water is added in it at the construction field (site), can be used after stirring evenly.Grouting material has certainly
Good fluidity, fast hard, early strong, high-strength, ungauged regions, microdilatancy;It is nontoxic, harmless, not aging, pollution-free to water quality and ambient enviroment,
The features such as, antirust good from close property.There is reliable in quality in construction party face, the advantages that reducing cost, shorten the construction period and is easy to use.
Fundamentally change plant bottom case stressing conditions, is allowed to equably bear the whole load of equipment, to meet various machineries, electricity
The installation requirement of device equipment (jumbo high-precision grinder) is the ideal grouting material without the pad installation epoch.
Cement waterproof agent is a kind of chemical admixture, is added in cement, when cement setting hardens, volume expansion therewith,
Play compensation contraction and tension reinforcing steel bar generates prestressing force and is sufficient filling with cement gap.Waterproofing agent also known as waterproof essence block up
King, leak stopping spirit are leaked, waterproof material is divided into organic and two kinds inorganic.
Inorganic aluminate water-proof agent is the cement mortar of material, concrete waterproofer based on inorganic matter.It is anti-with waterproof
It oozes based on function, while having microdilatancy concurrently, increasing compactness function, it is strong to be configured to diminishing, slow setting and morning according to requirement of engineering
Etc. models.The waterproofing agent good water-proof effect, construction is simple, and project cost is cheap, is suitable for mortar, concrete structure underground work
Rigid structure itself waterproof of the new constructions such as journey, pond, water tower, bridge, culvert, tunnel, harbour, dykes and dams power station.
Polyethylene fibre can be added in existing grouting material simultaneously, and polyethylene fibre tensile strength is low, elongation percentage mistake
Long, its influence grouting material mobility.
Invention content
It is an object of the invention to：In view of the above problems, it discloses a kind of for reinforced masonry wall grouting material, spy
Sign is, according to parts by weight, including：
Cement；
Water；Its quality accounts for the 12%-15% of grouting material；
