Abstract
The effects of partially replacing of cement with glass powder in concrete were studied and therefore found that some extent could be replaced which contributes in strength development. Cement was partially replaced with glass powder at varying percentages such as 10%, 20% and 30% and several concrete cylinders were casted along with plain concrete specimen. The cylinders were tested for compressive strength and split tensile strength at the age of 7, 14 and 28 days and were compared with the results of plain concrete. The overall test results indicated that the waste glass powder could be utilized in concrete as a good substitute of cement up to particle size less than 75μm. In replacement of cement with glass powder of 10%, the compressive strength and split tensile strength were reduced in 7th days for all samples. The 20% replacement of cement by glass powder met maximum compressive strength as compared to that of plain concrete. At 28 days, 30% replacement of cement by glass powder met maximum split tensile strength as compared to that of plain concrete.
Highlights
Concrete is widely popular throughout the construction industry due to the various advantages of accessibility, availability and economy associated with it
Cement is the main components of concrete, which works as a binder between coarse aggregate and fine aggregate, with the help of water
Compression Testing Machine (CTM) of capacity 2000 KN was used for both compressive strength test according to ASTM C39-C39M-17 [10] and split tensile strength test according to ASTM C496-C496M-11 [11] of concrete cylinder as shown in Fig. 12 and Fig. 13
Summary
Concrete is widely popular throughout the construction industry due to the various advantages of accessibility, availability and economy associated with it. It is made by the mixing of binding material, generally cement, fine aggregate and coarse aggregate with water. Cement is the main components of concrete, which works as a binder between coarse aggregate and fine aggregate, with the help of water. It has own environmental impacts and contributes largely to concrete. Environmental issues are playing an important role in the sustainable development of the cement and concrete industry.
