Abstract

This research will discuss about the compressive strength of concrete by using superplastisizer as an addictive substance and waste of carbide weld as the admixture material of cement replacement. Through this research is expected to know the right composition to produce a concrete formula with high quality by utilizing the existing local waste dan superplastisizer (Viscocrete-10). In this study made a sample of concrete cylinders measuring 15 cm diameter with a height of 30 cm totaling 63 specimens with 7 variations with each variation made as many as 9 specimens. The compressive strength test was performed at age 7, 14 and 28 days. Through this research, the result of flowability, compressive strength and elastic modulus of each test object variation.

Abstract

This research was conducted to compare several regulations that evaluate the level of vulnerability of school buildings in Yogyakarta. The regulations used in this study are a guide to assessing and repairing damage to public housing buildings due to the earthquake according to the Department of Public Works in 2000, technical guidelines for safe school rehabilitation according to the National Disaster Management Agency in 2011, a broken one or two-story simple building block safety check guide due to the earthquake according to the 2009 World Seismic Safety Initiative and using rapid visual screening of building for potential seismic hazards according to the Federal Emergency Management Agency No. 154 of 2002. The 25 schools selected in this study were located in areas prone to earthquakes, volcanoes erupted and prone to landslides. Through this research, the results of the appropriate regulations were obtained to evaluate the rapid level of vulnerability of buildings to disasters and evaluation of certain disaster cases was needed because the regulations did not accommodate all types of disasters.
