Studies on Glass Powder as Partial Replacement of Cement in Concrete Production
Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of green house gases, such as CO2, to the atmosphere. Among the greenhouse gases,CO2 contributes about 65% of global warming. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmospher...
متن کاملLimestone and Silica Powder Replacements for Cement: Early-Age Performance.
Developing functional concrete mixtures with less ordinary portland cement (OPC) has been one of the key objectives of the 21st century sustainability movement. While the supplies of many alternatives to OPC (such as fly ash or slag) may be limited, those of limestone and silica powders produced by crushing rocks seem virtually endless. The present study examines the chemical and physical influ...
متن کاملPartial Replacement of Metakaoline in Cement Concrete
Concrete is the extensively used construction material in the world. However, environmental concerns both in terms of damage caused by the extraction of raw material and CO2 emission during cement manufacture have brought pressure to reduce cement consumption by the use of supplementary materials. The utilization of calcined clay, in the form of metakaolin (MK) in concrete has received consider...
متن کاملExperimental Investigation on Glass Powder as Partial Replacement of Cement for M - 30 Concrete
Glass is needed in several forms in today’s life. Its life is limited, and after use it is either stored into sharp edged or sent to landfills. As we know glass is non-biodegradable, landfills does not recommend any environment friendly solution. In India as a most developing country, facing shortage of post consumer’s disposal waste site and it’s become very serious problems. Hence, there is s...
متن کاملPrediction of Lightweight Aggregate Concrete Compressive Strength
Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the main methods of non-destructive testing in the assessment of compressive strength...
