摘要

研究了粉煤灰和鸡蛋壳粉对混凝土抗压强度、和易性、密度和吸水率的影响。本试验分别在3日龄、7日龄、14日龄和28日龄分别使用粉煤灰废物和鸡蛋壳粉进行试验，粉煤灰废物变化量为15%，鸡蛋壳粉变化量为10%和17.5%。对于所使用的测试对象，测量直径为10厘米，高度为20厘米的测试对象多达36个测试样本，通过每天的变化多达3个测试对象样本。试件2中掺有15%粉煤灰废料和10%蛋壳粉的混凝土，龄期28天抗压强度为29.45 Mpa。普通混凝土试样在龄期28天的抗压强度为30.37 MPa。试验样品3的变异在28天龄期抗压强度为21.16 Mpa。

The Effect of Concrete Mixture on Usage Fly Ash and Chicken Egg Shell Powder as Cement Substitutions in Concrete Compressive Strength

The purpose of this study was to determine the effect of utilizing fly ash and chicken egg shell powder on the compressive strength of concrete, workability, density and water absorption. In this study, testing was carried out with the use of fly ash waste and chicken egg shell powder with variations of 15% fly ash waste and variations of chicken egg shell powder by 10% and 17.5% at the age of 3 days, 7 days, 14 days, and 28 days. for the test objects used measuring with a diameter of 10 cm and a height of 20 cm as many as 36 test samples by making variations of the day as many as 3 samples of test objects. Concrete with a mixture of 15% Fly Ash waste and 10% Egg Shell Powder in test sample 2 obtained a compressive strength at the age of 28 days of 29.45 Mpa. Variation of the Normal Concrete sample got a compressive strength at the age of 28 days of 30.37 MPa. Variation of test sample 3 got a compressive strength at the age of 28 days of 21.16 Mpa.
