The present paper centers around the researching attributes of M50 evaluation concrete with replacement of cement with Ground Granulated Blast Furnace …
Concrete buyers and specifiers should recognise these issues and decide how best to align their ambitions to reduce emissions both on-site and globally. GGBS is an excellent supplementary cementitious material that helps displace clinker demand globally. However, GGBS is a limited and constrained resource that is almost fully utilised globally.

L INDRA SENA REDDY et al. (2021) The present evaluation focuses on optimal utilization of GGBS on M50 grade of concrete with various proportions mixes (0%, 10%, 20%, 30%, 40%) and replacement of …
The Green and Gracious Builder Scheme (GGBS) was introduced in 2009 to raise the environmental consciousness and professionalism of builders. It is also a benchmark of a builder's corporate social responsibility to the environment and public during the construction of projects. It aims to: Set standards for gracious practices.
It is apparent that GGBS at the weight fraction of 40% improves the ITZ microstructure at most. Download : Download full-size image; Fig. 7. Aggregate–mortar ITZ modality in HPC containing GGBS as a partial replacement Portland cement (The left side of the micrograph shows aggregates and the right presents cement paste).
High-performance computing (HPC) is technology that uses clusters of powerful processors that work in parallel to process massive multi-dimensional data sets, also known as big data, and solve complex problems at extremely high speeds. HPC solves some of today's most complex computing problems in real time.
Abstract. This study aims at replacing sand and cement with ROBO sand and ground granulated blast furnace slag (GGBS) in the concrete mix. Here, GGBS and …
High Performance concrete is prepared with help of the guideline give by ACI-211-4R and in accordance with IS- 10262-2009, by using various cementitious martial like Fly Ash, Silica fume, Alccofine as a mineral admixture. various w/b ratio is used for achieving the different compressivestrength of concrete and its relative workability.

Hui-sheng et al. studied the influence of GGBS on the compressive strength of HPC up to the age of 180 days. GGBS contents were 0, 15, 30, 45 and 60 % by weight of cement, with water-binder ratio of 0.30 and 0.35. It was observed that HPC with GGBS at w/b of 0.30, compressive strength reached highest value at optimum replacement of 15 %.
GGBS's use to reduce greenhouse gas (GHG) emissions in concrete needs to be carefully considered. A group of 13 experts from across structural engineering, concrete and cement industries, construction, academia, and civil society have collaborated on a paper that reviews the use of ground granulated blast furnace slag (GGBS) in …
Like MK, the partial replacement of cement with GGBS influences the concrete by reducing the pore structure of the concrete pastes (Malhotra 2008, Qu et al. 2021); thereby, reducing penetration rate of deleterious substances of the marine environment. It is worth noting that the porosity of GGBS-induced HPC decreases with age (Qu et al. 2021).
