The specific proportions and manufacturing processes would depend on the desired characteristics and local building standards. This practice aligns with the broader trend in construction toward using recycled materials and optimizing the performance of building components.
Concrete has become a vital part of our lives. The use of concrete is increasing at a very high rate. one of the main constituents of concrete is ordinary Portland cement. The manufacturing of cement results in emission of large amounts of CO2. Thus, the researchers have started finding alternatives for the partial replacement for cement. GGBS is used to make durable concrete structure in combination with ordinary portland cement / or other pozzolanic material. crumb rubber is used in brick, manufacturing to enhance the bricks properties such as durability and insulation it helps recycle rubber waste making the process more sustainable. The bricks are tested for its compressive strength, water absorption, efflorescence, carbon attack test after 14 days and 28 days of curing. The replacement percentages of cement by 10% crumb rubber and GGBS used are 5,10,15 and 20%. water cement ratio adopted in this work is 0.50. For this ratio we got maximum strength for 15% cement is replaced by GGBS. Hence up to 15% GGBS for cement and 10% crumb rubber for fine aggregate can be replaced to get good results.
The combination of crumb rubber and GGBS in masonry bricks reflects a sustainable and technologically advanced approach to construction materials, aligning with efforts to create environmentally friendly and resilient structures. Therefore, in this work we are using crumb rubber and GGBS as principal materials for masonry bricks. 2. PROBLEM STATEMENT The issues of tyres disposal present a multifaceted challenge with far-reaching implications. Improper tyre disposal poses significant environmental risks, contributing to soil and water pollution while releasing hazardous substances.
Key Words: Crumb rubber, GGBS, Carbon attack, efflorescence.
Moreover, challenges in tyre recycling process, including inefficient methods and insufficient infrastructure, hinder sustainable disposal efforts addressing these problems requires a comprehensive approach, including policy analysis to improve regulations, innovative solutions for responsible disposal.
1. INTRODUCTION Crumb rubber is a term usually applied to recycled rubber from automotive and truck scrap tyres. During the recycling process steel and fluff is removed leaving Tyre rubber with a granular consistency. Continued processing with a granulator and/or cracker mill, possibly with the aid of cryogenics or mechanical means, reduces the size of the particles further. It is not possible to discharge the rubbers in the environment because they decompose very slowly and cause lots of pollution. So, it is necessary to have a relevant use of these wastages. These waste materials can be used to improve some mechanical properties of concrete. Addition of rubber to concrete results in the improvements of some mechanical and dynamical properties. Such as more energy absorption, better ductility and better crack resistance. By using the waste tyre (crumb rubber) one can reduce the harmful effect on environment and provide sustainable concrete.
The utilization of GGBS masonry brick construction presents an opportunity to enhance sustainability. However, the current challenge lies in determining optimal proportion and application method of GGBS. 3. OBJECTIVES The objectives of this study are:
