As the manufacture of one ton Portland cement releases about CO2 into atmosphere, and since burning lime stone directly, industry is responsible for around 7% global emissions. In calcination process, calcium carbonate in limestone transformed oxide carbon dioxide. This step alone half industry's footprint. The use fossil fuels to heat kiln results indirect When these are used, they contribute ...

The construction industry faces a challenging situation in attaining sustainable development goals. carbon footprint of the production and use materials such as ordinary Portland cement concrete products is still on rise despite many alternatives technologies. In this paper, local cross-organizational learning approach (COLA) systematic review academic professional literatures were applied anal...

Abstract Geopolymer in recent years is being deemed as a promising alternative to cement concrete, which has remained backbone of the construction industry. Despite GPC having potential capability reducing carbon footprint, still many its characteristics and mechanism be investigated. The present study represents utilization bagasse ash production geopolymer concrete. In order reduce ecological...

In response to the high carbon emissions and energy consumption of traditional cement curing agents, in this paper, we propose a fly ash/slag-based geopolymer as an alternative for stabilizing soft soils. study, effects activator modulus, activator, slag content on geopolymer-stabilized clay were investigated by unconfined compressive strength (UCS) tests Hangzhou soils, water stability resista...

Summary In oil and gas geothermal well construction, a cementitious material is pumped in the wellbore to provide zonal isolation support casing during life cycle of well. Thus, barrier materials must be durable terms chemical mechanical properties have compatibility with pipe. The complex region casing-cement interface considered key parameter fulfill long-term isolation. This chemically stabl...

Portland cement concrete is the most commonly used construction material in world for decades. However, searches technology are remaining growing to meet particular properties related its strength, durability, and sustainability issue. Thus, several types of have been developed enhance performance. Most modern contain supplementary cementitious materials (SCMs) as a partial replacement cement. ...
