Abstract - This paper presents an experimental study on the effect in strength of foam concrete using three different filler materials such as river sand, sea sand and quarry dust with cement. Cement and filler mixed in proportions 1:0, 1:1, 1:2 and 1:3 in weight basis.The foaming agent was added with water and mixed thoroughly. Mixed cement and filler added slowly with this and after certain minutes this gel poured in to the mould of size 19 x 9 x 9 cm to get the brick specimen. The specimens were water cured for 28 days. The compressive strength of this light weight foam concrete bricks at an age of 28 days was obtained at normal temperature. Then the specimens after 28 days curing were heated to 100°C in an oven for 24 hours and tested. Also the specimens kept at 100°C for 24 hours were suddenly immersed in water and subjected to thermoshock and tested for compressive strength. The loss of strength due to thermal and thermo shock effect were compared with conventional concrete (River sand as filler). From the results, it is found that sea sand as well as quarry dust can be used as alternate filler material for natural river sand in foam concrete. Key Words: Foam concrete, Foaming agent, Cement, Sea sand, River sand, Quarry dust.
1. INTRODUCTION Foam concrete is nowadays largely used in construction industry due to light weight and easy preparation. It occupies the portion to fill better than any other compound. Uniform distribution of air bubbles through the mass of concrete makes 20% of entrapped air, which makes it so light than the conventional concrete. Foam concrete has been successfully used and it has gained popularity due to lower weight. For foam concrete, generally river sand is used as filler material. Due to rapid usage, there is a shortage of conventional construction material river sand and so costly one. In order to minimise this it is necessary to think of alternate materials.It is observed from previous study that © 2017, IRJET

the maximum ratio of cement with filler for foam concrete as 1:2.5, so in this study we fixed the trial mixes from 1:0 to 1:3 to confirm the maximum ratio. This is an experimental study on how the strength of foam concrete varied when sand is replaced by sea sand as well as quarry dust.
