With the ability of resisting erosion of sulfate；Methyl silicate in the present invention is space network, is a kind of from benthos
Powder, methyl silicate and caused bubble (CO in cement hydration process are shunk in heavy sand superfines, also known as deep-sea2Deng gas) with
And water reaction, methyl silanol class material is formed, change reticulates organosilicon, therefore raw material of the methyl silicate as GRC products, can
Caused bubble and unnecessary moisture in cement hydration process are eliminated, moistureproof, impermeable, waterproof and stain resistance is improved, also carries
The high life-span of GRC products.
Water reducer, metakaolin, volcanic ash and methyl silicate are combined as enhancer and are used as GRC systems by the present invention
The raw material of product, mixed with cement, glass fibre, quartz sand, water and rubber cement, water reducer, metakaolin, volcanic ash and methane-siliconic acid
Salt can produce synergy between each other, GRC products is had extraordinary toughness, bending resistance and tensile capacity, to greatest extent
Extend the service life of GRC products, GRC products are used in building, and GRC products and building itself can be made of the same age.In addition, this hair
Material used in bright is all from natural or Litter reprocessing, has the good feature of environmental protection.

Layer is identical), for the number of plies of its thickness and injection depending on the thickness of regulation, every layer of jet thickness is about 3~4mm；
(3), it is stripped and conserves：
During the demoulding, GRC plates (GRC products) need uniform fulcrum, and maintenance area is immediately entered after the demoulding and is conserved, is supported
The shield phase is 28 days；
(4), it is surface-treated and repairs：
GRC components during the demoulding, which are easily damaged, to be peeled off, or bubble and honeycomb that diameter is more than 2mm are produced in some positions
Deng should be repaired using above-mentioned cement mortar；
(5), store and carry：
The storing mode of GRC products is generally kept flat, because providing appropriate support to prevent it from toppling over when standing up；
Storage location should be smooth, must not ponding, ground should have enough endurance, and memory device must not have any uneven
Depression；
During carrying, the surfaces of GRC products clashing and breaking or can not have any pollution, and avoid bearing extra pressure.
Above-mentioned GRC products also need to carry out quality control, and test sample must be with survey of 28 days material age according to CNS, BSI or ASTM
Examination specification is tested.
Beneficial effects of the present invention：The present invention is using the combination of water reducer, metakaolin, volcanic ash and methyl silicate as increasing
The strong factor and the raw material as GRC products, and mixed with cement, glass fibre, quartz sand, water and rubber cement, water reducer, higher ridge
Soil, volcanic ash and methyl silicate can produce synergy between each other, GRC products is had extraordinary toughness, bending resistance
And tensile capacity, to greatest extent extend GRC products service life, GRC products be used for build in, can make GRC products with
Building itself is of the same age.In addition, raw material used in the present invention is all from natural or Litter reprocessing, there is good ring
Guarantor property.
