Abstract - This project deals with development of floating
increasing urban development and population, demand of sustainable structures increased. However, by use of the waste materials, the environmental impact may be reduced. Sustainable by products from various industries reduces overall cost and energy. By incorporating industrial by products in concrete meet out the requirement of creating the environmental awareness in the society. Now a days more awareness has been paid to the development of light weight aggregate structure having low unit weight and sufficient strength. One of the way to reduce the weight of the structure is by using the light weight aggregate concrete which is most probable method in reducing the weight of the structure.
concrete by using lightweight aggregates (pumice stone) and other replacing material (scoria). There are many types of lightweight concrete which can be produced either by using lightweight aggregate or by using an air entraining agent. In this study we have worked on combination of above mentioned types. This concrete is a non-structural concrete. In this study, pumice stone is used as replacement materials in concrete where it is found in the abyssal of the red clay. The physical, mechanical and durability properties of concrete was investigated by conduction compressive strength on the ordinary and replaced concrete with varied percentage of pumice from 5% to 30%. It's observed that environmental and economical benefits can be achieved if waste materials can be used to replace the coarse aggregate in order to use the waste materials effectively in areas with abundant availability of materials. Along with pumice, The aim of this project is to analyse the suitability of scoria as a fine aggregate for concrete production and its effect on the properties of concrete. A differing ratio of scoria was considered as a partial replacement of fine aggregate with river sand after analysing its engineering properties, and its effect on the mechanical properties of concrete were examined. The test results on the engineering properties of scoria revealed that the material is suitable to be used as a fine aggregate in concrete production. The replacement of scoria with river sand also enhanced the compressive strength of the floating concrete.
2.OBJECTIVE The main objective of this project is to increase compressive strength of the Floating concrete by using lightweight aggregates.
3.SCOPE The present data indicates that there is significant improvement in the strength properties of the lightweight concrete by using different admixtures. Further improvement in the study can help to increases the mechanical properties of lightweight concrete by adding different combination of materials.
Key Words: Pumice stone, Scoria powder, Conventional concrete, Compressive strength.
1.INTRODUCTION Concrete can be defined as composite material, composed of cement, aggregate, water and admixtures in required proportions. It is considered to be most important and useful materials for many constructional activities . The basic ingredients for a concrete are Portland cement, water, and aggregates. Concrete is generally considered to be the most widely used material on Earth. It can be easily moldable to any shape in the elastic stage. Aggregate is a broad category of coarse particulate material most widely used in constructional activities. Aggregate act as a reinforcement in a concrete contributing compressive strength to concrete. With the
