Pengaruh aditif limbah kerang darah (anadara granosa) terhadap kualitas beton K-225

A rapid development of the concrete construction sector has resulted in an increase need for raw materials that are obtained directly from nature. The environmentally friendly is also increasing along with engineering technology, so several studies have been conducted to search alternative additives or mixtures. Anadara granosa clam shell can be utilized as one substitute material coarse aggregates. In this research, shells 10% and 13% were added normal mixtures, aged 28 days, then analyzed characteristics compressive strength. From analysis results, it was found strength up 103.67% 233.47 Kg/cm2 addition while more than reduce Scanning Electron Microscopy results showed a relatively rough surface many pores on due shell. Finally, concluded used maximum total weight concrete.
