“…Particles are formed from the pointed and angular ends of silica. The bond between Mount Merapi sand and cement is stronger because Merapi sand has an angular pattern of particles [15]. This research was conducted with the aim to know the effect of adding gypsum and lime to the compressive strength, bulk density and water absorption of lightweight interlock bricks using fine aggregate of Merapi sand.…”

Lightweight materials will reduce the earthquake forces received by the structure. Interlock lightweight brick is a new innovation in the building industry that functions as wall material. Utilization of local materials in Central Java-Yogyakarta, namely Merapi sand, needs to be developed to maximize its potential utilization as an aggregate of lightweight interlock brick. In many research, lime and gypsum as additives have been shown to improve the quality of concrete. This study aims to determine the characteristics of the addition of gypsum and lime as an added material for lightweight interlock bricks with fine aggregate of Merapi sand. The standard of test object and the test refers to SNI 8640-2018. The results showed that in dry weight all the mixed variations were categorized in the 900 kg/m3 and 1100 kg/m3 classes. All variations also complied with water absorption requirements in SNI 8640-2018, but only variations of 2.5% gypsum addition and 5% lime addition meet the compressive strength requirements. This mixture has the highest average of compressive strength value compared to other mixtures. Based on SNI 8640-2018 lightweight interlock bricks with the addition of 2.5% gypsum and 5% lime can be used as wall bricks.

Silica gel was synthesized from Lapindo mud by the sol-gel process. XRF analysis confirmed that Lapindo mud contained silica (50%) which was major components, therefore Lapindo mud has great potential as a raw material for silica gel synthesis. Metal silicates commonly used as a precursor to prepare silica gel. A Lapindo mud was mixed with an alkaline solution, stirred and heated to prepare metal silicates. Hydrochloric acid was then slowly added to the metal silicates solution to obtain silica gel. The pH 4 selected as the optimum pH in the synthesis of silica gel. The purity of synthesized silica was determined by XRF and shown that silica purity by 100 mL sodium hydroxide 6 M (4 h, 80 °C) treatment was 63.25% with optimum yielded 32.3%. Whereas 12 M potassium hydroxide 200 mL (5 h, 90 °C) treatment could be produced better purity up to 77.71% with a yield of 39.72%.
