Utilization of Rice Straw Ash as a Replacement of Cement and Fine Aggregate in Mortar Mixes

Blitar Regency is one of the strange culinary centers, among which are processed various foods from snail base ingredients, ranging from kripik, sate oseng-oseng and so on as well as the existence of Blitar district is one of the rice barns in East Java. With the existence of Blitar district as a snail-based culinary producer and one of the rice barns in East Java, this is not spared from several problems, such as the disposal of snail shells in the river and burning of rice straw in rice fields which both will cause environmental damage. This study aims to examine the use of snail shell ash and rice straw ash as a substitute material for cement in mortar mixtures against mortar compressive strength. The research method used was the experimental method by mixing fine aggregate main ingredients with snail shell ash and rice straw ash then testing the compressive strength. The results of the compressive test with the addition of the percentage of snail shell shell turned out to increase by 54.78%.

Abstract This research paper highlights the Rice Straw Ash (RSA) which is an agriculture wastage from rice cultivation and milling processes can be utilized in construction work. Compressive strength is increased due to replacement of rice straw ash up to 12.5% and also 10% cement replacing, it also increases the initial and final settlement time of mortar. By replacing of 10% RSA, the compressive strength is step by step increased and also by replacing the cement ratio the property of mortar (Water permeability) is depended and so as age of mortar. We can simply describe it that, by increasing age and compressive strength of mortar the permeability is decreased. Permeability of RSA mortar depends on the cement substitution percentage of RSA and age of mortar. When the permeability decreases, the compressive strength of mortar also increases.
