The use of waste glass as a partial substitution for fine aggregate in concrete design

摘要: The objective of this thesis is to investigate the long term effects waste glass as av partial substitute for fine aggregate in concrete. This aims expand on body of research conducted by Kenneth K. his Bachelor Engineering – “The Applications Recycled Crushed Glass Civil Construction Northern Territory”. Early suggests that using concrete will stimulate Alkali Silica reaction (ASR). ASR occurs over a time between an alkaline base and a non-crystalline silica reactant. In case acid-base calcium hydroxide (Ca(OH)2) found cement paste silicic acid (H4SiO4) in the cullets. can be simplified follows Ca(OH)2 + H4SiO4 → Ca2+ H2SiO42− 2 H2O CaH2SiO4 · alters volume results swelling cracking of structure. A preliminary sieve analysis composite have denser gradation than alone. dense gradation most air voids materials are filled with smaller particles (Mamlouk et al, 1999). This means amount voids within future mix could reduced the more densely graded aggregate. reduction further increase the overall strength mix. difference density cullet was to be about 11.5% which noticeable difference. composite aggregate changing significant effect compressive It predicted the compressive mixes suffer percent substitution increases decreases.
