The quality of the construction material is required to be improved to enhance the strength and performance of the structure. From the earlier days, admixture assumes a crucial job in cement to improve the basic properties. Before knowing about the admixtures, good knowledge regarding concrete is required. In this work, an endeavor was made to contemplate the conceivable outcomes of utilizing tamarind kernel powder, a naturally available biowaste material which is a hydrocolloid in nature, as an admixture in concrete. The addition of tamarind kernel powder was varied from 0.25 to 1.25% in proportion to the weight of cement used. A huge amount of tamarind seed wastes are produced every year especially in India it is nearly 97,000 metric tons per year. In the absence of waste disposal, the utilization of tamarind seed for concrete improvement will be a great development. In this research article, tamarind kernel powder was added to fresh concrete and relevant tests were conducted on fresh and hardened concrete before and after the addition of tamarind kernel powder. Further, nondestructive tests were also carried out on concrete added with tamarind kernel powder. The concrete shows good enhancement in strength until the addition of 1% of tamarind kernel powder to the weight of cement. Moreover, the workability, mobility and compaction factor results obtained in this experiment show that the optimal addition of tamarind kernel powder does not affect the properties of fresh concrete. The tests on hardened concrete and results obtained from nondestructive testing methods confirm the same. Hence, this experimental work shows that the natural hydrocolloid, that is, tamarind kernel powder can be added to an amount of 1% to the weight of cement which shall not affect the other parameters of concrete but increases the strength considerably.

添加罗望子仁粉的普通水泥混凝土强度参数研究

需要提高建筑材料的质量以增强结构的强度和性能。从早期开始，外加剂就在水泥中起着至关重要的作用，以改善其基本性能。在了解外加剂之前，需要对混凝土有充分的了解。在这项工作中，人们努力考虑使用罗望子仁粉（一种天然可得的生物废料，其性质为水状胶体）作为混凝土中的掺混料的可能结果。罗望子仁粉的添加量与所用水泥的重量成比例为0.25-1.25％。每年产生大量的罗望子种子废料，特别是在印度，每年近97,000公吨。在没有废物处理的情况下，利用罗望子种子进行具体改良将是一个巨大的发展。在这篇研究文章中，将罗望子仁粉末添加到新鲜混凝土中，并在添加罗望子仁粉末之前和之后对新鲜和硬化的混凝土进行了相关测试。此外，还对添加了罗望子果仁粉的混凝土进行了无损检测。在向水泥重量中添加1％的罗望子仁粉末之前，混凝土显示出良好的强度增强。此外，在该实验中获得的可加工性，流动性和压实因子结果表明，罗望子仁粉的最佳添加量不会影响新鲜混凝土的性能。对硬化混凝土的测试以及从无损测试方法获得的结果证实了这一点。因此，
