Abstract

In recent time quarry sand is being extensively used in concrete due to environmental concerns leading to restrictions on use of natural sand. The extensive research publications broadly indicate suitability as well as limitations of quarry sand use in concrete. Most of the literature relates the performance of quarry sand concrete in various combinations adopted by researchers. The need is felts by authors to identify some factors directly related to strength parameters. The authors tried ninety different combinations covering M25, M30 & M40 grade of concrete containing various amounts of cement, quarry sand, natural sand and fly ash. Authors observed that quarry sand to natural sand ratio is an important factor governing development of compressive strength, split tensile strength and flexural strength of concrete mixes consisting of quarry sand and natural sand. It has been observed that strength parameters go on increasing with quarry sand to natural sand ratio up to 0.9, there after strength goes on decreasing. The critical analysis of data compiled was used to develop mathematical models for estimating compressive strength split tensile strength and flexural strength at various ages. The models were tested for own result and result from references. It is observed that the mathematical models are realistic and justify the relevance of quarry sand to natural sand ratio in development of strength.
采石场砂和天然砂比在实现不同强度方面的相关性
近年来,由于环境问题导致天然砂的使用受到限制,采石场砂被广泛用于混凝土中。大量的研究出版物广泛地指出了采石场砂在混凝土中的适用性和局限性。大多数文献涉及采石场砂混凝土的性能在各种组合采用的研究人员。作者认为有必要确定与强度参数直接相关的一些因素。作者尝试了90种不同的组合,包括M25、M30和M40级混凝土,其中含有不同数量的水泥、采石场砂、天然砂和粉煤灰。研究发现,采石砂与天然砂的配比是决定采石砂与天然砂混合混凝土抗压强度、劈裂抗拉强度和抗弯强度发展的重要因素。当采石场砂与天然砂比达到0.9时,强度参数继续增大,之后强度继续减小。对收集的数据进行关键分析,以建立估算不同年龄的抗压强度、抗拉强度和抗折强度的数学模型。用自己的计算结果和参考文献的结果对模型进行了检验。结果表明,所建立的数学模型是真实的,证明了采石场砂与天然砂比在强度发展中的相关性。
