玻璃纤维增强水泥制品(grc)及工艺（Glass fiber reinforced cement products (GRC) and process） Glass fiber reinforced cement (GRC) and.Txt18 process with honesty, abandon the false; with honesty, to abandon the boring; with ease to abandon the impetuous, whether intentionally discarded, or accidental loss, as long as ever have, in some cases, generous abandon is also a kind of realm. Glass fiber reinforced cement products (GRC) and process Glass fiber reinforced cement (Glass, fiber, Reinforced, Cement, abbreviated as GRC) is a composite material made of glass fiber as reinforcing material and cement paste or cement mortar as matrix. From the perspective of the development of building materials industry, large building materials must be green materials for sustainable development. Cement and cement based materials are the largest man-made materials nowadays. World cement production has more than 1 billion 500 million T (our current cement production has reached the world cement output 1/3), based on projections, the total cementitious materials in 60-70 billion T. The main resource consumed is estimated to be 1 billion 500 million T of high-quality limestone. Sandstone aggregate 4 billion m3, emissions of COsub2/sub (major greenhouse gases) more than 12t, there are other harmful gases and a large number of dust, seriously polluting the environment. Today, Chinas annual output of cement remains at 500 million T, according to a reasonable index to estimate the annual energy consumption. Resources and the environment caused by the burden as shown in table 5-4. Therefore, regardless of our country, or the rest of the world, we must rely on science and technology, manpower, energy conservation, environmental protection, or cement and cement based materials will become unsustainable materials. Cement-based materials must be developed to high performance, to reduce dosage, prolong life, enhance functionality, and especially reduce environmental costs. Since the Portland cement came into bei
