【摘要】 根据土木工程中大量的墙面砂浆开裂和渗漏现象的统计结果,本文分析了矿物掺合料对砂浆质量的影响,并采用灰色系统理论建立了相应的预测模型,根据所建立的理论模型对砂浆的收缩率进行了预测.结果表明,理论预测结果与实测资料基本吻合,本文所给出的理论模型令人满意.更多还原

【Abstract】 Based on statistical results of a large amount of the crack and seepage of surface coat on the wall in civil engineering,the influence for mineral addition to mortar performance are discussed.The fundamental grey system model for the influence of mineral addition to mortar performance is established by using the theory of grey system.And the model is used to predict the contraction of the mortar.The agreement of the theoretical results with the measurements shows that the model is satisfactory.更多还原
