Abstract
High-quality concrete is increasingly used in infrastructure development so it can increase the price of raw materials in the market. To handle these problems, it is necessary to carry out material innovations which later these innovations can also overcome environmental problems is use glass waste for replace some of the sand and fly ash substitutes for cement. 1 In addition, to increase the quality of high-quality concrete, the addition of superplasticizer to the concrete mixture is carried out. This study reviewed the use of fly ash, glass waste, and superplasticizer as concrete mixture materials against the value of modulus of elasticity, compressive strength of concrete, and absorption concrete. Experimental method used for this research using two cylinder sizes, namely 15 x 30 cm as many as 18 samples for compressive strength and modulus of elasticity and 10 x 20 cm as many as 3 samples for absorption. The mixture planning used American Concrete Institute (ACI) method with variations of 10% fly ash, 12.5% glass waste, and 0.75% superplasticizer. Then, 15% fly ash, 12.5% glass waste, and 0.75% superplasticizer. Finally, 0% fly ash, 0% glass waste, and 0.75% superplasticizer. The test results found that the use of fly ash, glass waste, and superplasticizer together can improve the value of modulus elasticity and compressive strength. The greatest compressive strength values in variations of 10% fly ash, 12.5% glass waste, and 0.75% superplasticizer were 40.57 MPa at 14 days old and 45.85 MPa at 28 days old. In addition, the largest variation also obtained the value of modulus of elasticity, namely 30657 MPa aged 14 days and 32561 MPa aged 28 days. The lowest absorption value was obtained at 2.57% in variations of 15% fly ash, 12.5% glass waste, and 0.75% superplasticizer. With these results, the use of fly ash, waste glass, and superplasticizers together can increase modulus of elasticity and compressive strength and can reduce the absorption value of ordinary high-quality concrete.
