The essay researched the compressive strength, bending strength, impact resistance and abrasion resistance of high strength polypropylene fibermesh concrete the mechanism of enhancing the properties of high strengh poloypropylence fibemesh road concrete composite was discussed and analyzed the regression on tensile strengh with portland cement mixed with fiber was derived using experiment the tensile strength of fiber soil stablization with porland cement was increased with dosage and length of fiber while the former was more effective than the latter test and analysis results indicate that polypropylene fiber can not only reinforce the strength of concrete, but also obviously promote the flexural fatigue life by the great stress the application of polypropylence fiber reinforced concrete in pavement construcion are also introduced
文章研究了不同摻量有機纖維混凝土的抗壓、抗折強度、抗沖及性能、疲勞性能及耐磨性等各種路用性能，綜合論述了有機纖維對水泥混凝土路用性能的影響。通過試驗闡述了纖維水泥混凝土各種路用性能與纖維摻量、長度間的關系。分析表明纖維水泥混凝土隨著纖維摻量和長度增加而增加，且纖維摻量對纖維混凝土抗拉強度的影響比纖維長度的影響更大。 -

復合硅酸鹽水泥 -
The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper. the experimental results indicate that the effect of single retarder, such as citric acid, is inferior to that of composite retarder which was made of blending citric acid with a few portland cement ( about 0. 5 ?, by weight ). the effect of different water - retention agents, such as polyvinyl alcohol ( pva ), carboxymethyl cellulose ( cmc ), and na - bentonite, etc., was also studied, and the results demonstrate that by means of adding organic and inorganic water - retention agent simultaneously the water - retention of plastering slurry can obviously be improved. the optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other
研究了分別以檸檬酸、檸檬酸與普通硅酸鹽水泥復合物作緩凝劑，調節粉刷石膏的凝結時間，並對比2種緩凝體系對石膏抗折、抗壓強度的影響.比較不同保水劑（聚乙烯醇、羧甲基纖維素）以及相同量的保水劑在不同工藝流程下保水效果上的區別.探索了有機保水劑和無機保水劑對粉刷石膏的保水性的影響.結果表明，檸檬酸與普通硅酸鹽水泥的復合緩凝劑比單純的檸檬酸更能有效地延緩建築石膏的凝結，同時建築石膏的抗折、抗壓強度降低幅度減小
