【摘要】 通过对实行水泥新标准后的部分室内试验及一航局各公司提供的抗冻混凝土的配合比设计试验资料进行统计分析,线性回归给出适用于水运工程的鲍罗米公式,同时验证了《水运工程混凝土施工规范》(JT J268-96)中最大水灰比、最小水泥用量在实施新水泥标准后是否满足设计要求。更多还原

【Abstract】 Statistic analysis is made on the data of some laboratory tests and the data of the design and tests of mix ratios of frost-resistant concrete provided by the subsidiary companies of CHECTianjin Port Const.Corp.after new cement standard is implemented.The Bolwme Equation applicable to marine engineering is then given by linear regression.The maximum water cement ratio and the minimum cement usage specified in the Code for Construction of Concrete in Water Transport Engineering(JTJ268-96)are also verified to see if they meet the design requirements after the new cement standard is implemented.更多还原
