EXPERIMENTAL INVESTIGATION ON M-SAND AND BASALT FIBER IN M25 GRADE CONCRETE

Concrete is the majorly used materials in all type of construction activites. It need a quality sources for obtaining good quality. It can achieve by only proper usage of these at appropriate quantities. Basalt fiber is a fiber when added provides an additional strength. The work carried in this project, replace fine aggregate with M-sand and basalt fiber as an additive to cement in various percentages. The determination of the compressive, flexural and tensile strength of M25 grade concrete is studied. The fine aggregate is completely replaced with M-sand and basalt fiber is added in 0%, 0.5%, 1% and 1.5%. Thus the changes in their compressive, flexural and tensile strength is observed for 14 days and 28 days and results are formulated and the optimum content of basalt fiber to be utilized for production of quality concrete is founded.

This paper describes the experimental investigation of relationship between splitting tensile strength and flexural strength with the compressive strength of concrete containing waste PET as fine aggregates replacement. Waste PET was reprocesses and used as the artificial fine aggregate at the replacement volume of 25%, 50% and 75%, Cylindrical and prism specimens were tested to obtain the compressive, splitting tensile and flexural strength at the age of 28 days. Based on the investigation, a relationship for the prediction of splitting tensile and flexural strength was derived from the compressive strength of concrete containing waste PET as fine agglegate replacement.

As we know that Foam concrete has been successfully used and it has gained popularity due to its lower density than normal concrete. Globally the construction activities are rapid and using huge amount of fine aggregate and cement. Due to continuous usage of large amount of sand and cement we are creating natural imbalance by CONTINUOUS mining of sand, lime etc., from natural resources, which causes many natural hazards and become threat to humans. As a responsible citizen of world everyone think to stop the usage of sand and cement in huge quantity for infrastructural activities. Fly ash is one alternative solution as a partial replacement of sand and cement with Alccofine. In this investigation we are replacing fine aggregate with fly ash and cement with Alccofine by usage of Using additive materials in foam concrete which provides not only workability, strength but also reduce overall cost. As reducing the quantity of sand and cement in foam concrete we conserve Green House effect and also other raw materials used for cement. Foam concrete produced with uniform distribution of air bubbles thoughout the mass of concrete. The density of foam concrete is a function of the volume of foam added to the slurry and the strength decreases as decrease in densities. This experimental investigation was designed for density of 800 kg/m3. This study was compiled in determination of workability, plastic density, water absorption and compressive strength of foam concrete. The test specimens has been casted and tested at the age of 7,14 and 28 days.
