The Effect Of Bagasse Ash Addition In The Eco-Cement Of Egg Shell And Simping Shell To Mechanical Properties
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
Construction of concrete has increased every year causing cement demand to increase. Based on data from the Ministry of Industry of the Republic of Indonesia in 2017 predicted that domestic cement demand will increase to 102 million tons. To meet the needs of the cement, Indonesian people use portlandcement. But the basic ingredients in the manufacture of portland cement is limestone, are non-renewable natural resources and diminishing supply. So another innovation is needed to make cement based on environmentally friendly and renewable natural resources. One of them is by utilizing the bagasse ash which is generated from the production of sugar factories, eggshells are usually discarded by the people of Indonesia after eating eggs and simping shells disposable after eating clam meat. Though simping shell and egg shell contains a lot of CaO compounds which are the basic ingredients in the manufacture of cement and ash of bagasse that contains a lot of SiO2 compounds that can be used as a glue in the manufacture of cement. So this research is done by making the samples of shell-based eco-cementsimping shells, egg shells and bagasse ash using clay. From the test of compressive strength, it was found that the optimum value at the addition of 0.75 bagasse ash of 4.08 kgf / cm2 with density of 949.6 kg/ m 3 and LOI of 20.8%. But this composite strength is still low compared to portland cement due to the low content of Fe2O3 and Al2O3 in the raw materials used. The superiority of the resulting eco-cement has the potential to be made as a lightweight brick because of the low density produced and without the combustion process (calcination) of raw materials. So further research is needed on the use of raw materials containing many of these compounds to strengthen the compressive strength.
