Abstract - Availability of river sand is becoming scarce, due
to rapid increase in infrastructure projects in India. Acute shortage of river sand, has led to indiscriminate sand mining. Adverse effect of sand mining includes river bank erosion, river bed degradation, loss of biodiversity and deterioration of river water quality and ground water availability. To address the above issues, research efforts are on, to find substitutes for river sand to be used as fine aggregate in mortars and concretes. One among the locally available resources is laterite. Laterite is a product of tropical or sub-tropical weathering, which is an abundant soil material in many parts of India. An attempt has been made to characterize the processing technique to obtain good quality lateritic fine aggregates (lateritic FA). Experiments were designed and conducted to study the performance of lateritic FA as replacement to river sand, in cement mortars and concretes. The river deposits are the most common source of fine aggregate. So there are great demands within the construction industries for river sand as fine aggregate used in the production of concrete. This has created a very difficult situation, also there is great fear from environmentalist and the ecology will be distorted. Hence, the need to find the materials which are affordable and available partially or totally replaced river sand in the production of concrete. Hence we are forced to think the alternative materials. This report aims to present the study done to establish scientific data regarding the compressive strength, tensile strength and flexural strength of concrete on partial replacement of fine aggregate with laterite soil in concrete mix of M-30 grade. The sand shall be replaced gradually in the mentioned grade of concrete by 0%, 10%, 20% and 30% with laterite soil and the specimen shall be tested at curing intervals of 3days, 7days, and 28days. For compressive strength and at curing interval of 3 days, 7 days, and 28 days for tensile strength as well as for flexural strength. Key Words: Laterite soil, steel fibers, super plasticizer (conplast Sp-430)
1. INTRODUCTION
assessment of its particle size distributions. There is, therefore, every reason to believe that this lateritic sand can be used in structural concrete production. The particle sizes of aggregates are known to affect the strength properties of concrete greatly. In related developments, substantial quantities of lateritic soil are found in heaps around the low as a replacement material in concreting operations. The focus of a good national development is to look inward with the intent to mobilize all-natural resources for economics purposes. One of the policy thrusts of the present government is to provide affordable housing for the people. Compressive strength is arguably the most widely used strength parameter for concrete. This may be due to the nature of concrete, being strong in compression and weak in tension. The use of lateritic as a partial sand replacer can help achieve this purpose and impact positively in reducing the cost of building materials. This study aims to proper documentation of the material to support their specification in design and construction.
2. OBJECTIVES
The objective of this study is to determine the strength of concrete by partially replacing river sand with laterite sand at 0%, 10%, 20%, and 30% and curing they concrete for 3days, 7days, and 28 days for compressive strength, tensile strength as well as for flexural strength.
Preparing the normal concrete by utilizing normal quality river bedded sand of Krishan river and ascertaining its strength via methods prescribed by applicable IS Codes of testing
Comparing the strength development of concrete and ascertaining the feasibility of using laterite soil concerning practically and economy of the study.
To conclude the effect of lateralized concrete concerning its adaption to normal mixes for equivalent gain of strength and economy of the mix so created.
Visual observation of the laterite material shows that the variation of sand is much sharper than those considered in previous works. This is confirmed by the preliminary © 2022, IRJET
