Abstract
Organic cement is an environmentally friendly alternative to Portland cement which is acquired by recycled organic waste and Mediterranean soil. Waste management is a global problem. The physical characteristic test results of the organic cement show that the weight test of fresh organic concrete is 2081kg/m³ and the dry weight of concrete is 2032kg/m³ which are smaller than Portland cement concrete's which are 2525kg/m³ and 2405 kg/m³ respectively. The fineness of alternative cement grains that passed the 200 mesh sieve is 56%, which is more than Portland cement's which is 52%. The solid weight of alternative cement is 1200kg/m3 whereas the solid weight of Portland cement is 1250kg/m3.
Highlights
IntroductionOrganic cement is the latest alternative to Portland cement and is made through organic waste recycling and Mediterranean soil substitution of Portland cement [2]
This study aims to develop previous experimental research which can be found in [1]
The references to the test method come from the American Society for Testing and Materials (ASTM) which include: ASTM C 188-95 for granular fineness/density tests [16], ASTM C 232-99 for fresh concrete bleeding test [17], and ASTM C 231-03 for air content of freshly mixed concrete [18]
Summary
Organic cement is the latest alternative to Portland cement and is made through organic waste recycling and Mediterranean soil substitution of Portland cement [2]. The necessity of building materials needs to be addressed by researching the utilization of recycling waste to obtain alternative building materials [3]. High waste volume has a negative impact on the environment, so handling of waste is necessary. Urban waste management in Indonesia is a real problem as population growth has an impact on the amount of produced waste and the occurrence of degradation problems that have the potential to cause social conflict to the communities [4, 5]. The high growth of waste volume coincides with high population growth rate. The waste management problem can be considered as a global problem
