The treatment of expansive soil is generally the most effective process for stabilization swelling clay. In this work, we will investigate influence an using granulated blast furnace slag (GGBS) alone and activated by cement (GGBS/C) mechanical, physical chemical tests. results obtained show increased pH, improved plasticity as well a significant reduction in potential pressure following percen...

Ground Granulated Blast furnace Slag (GGBS), a waste product from steel plants, can be effectively utilized as pozzolanic material and used partial replacement to cement leading sustainable construction practice. Mortar is usually binding plastering material; hence the chances of exposure damaging environment are high than concrete. GGBS mortar should examined for durability weathering action, ...

The present paper reports a statistical analysis of the performance of the blast furnace number X at the Bhilai Steel Plant over a period of sixteen years with the special reference to the quality and consumption of sinter . The variation in basicity and consumption of sinter, for the blast furnace data considered , is wide. The range of data covers high level to almost nil amount of raw limest...

In the field of construction, securing the early strength of concrete (on the first and third days of aging) has been an important problem in deciding the mold release time (i.e., shortening the construction time period). Therefore, the problem of reduced compressive strength in the early aging stage caused by mixing granulated blast furnace slag (GBFS) with concrete must certainly be resolved....

The purpose of this study was to evaluate the performance of porous vegetation concrete block made from blast furnace slag cement containing industrial by-products such as blast furnace slag aggregate and powder. The blocks were tested for void ratio, compressive strength and freeze-thaw resistance to determine the optimal mixing ratio for the porous vegetation block. An economic analysis of th...

Nowadays, cement manufacture is one of the most polluting worldwide industrial sectors. In order to reduce its CO₂ emissions, the clinker replacement by ground granulated blast-furnace slag and fly ash is becoming increasingly common. Both additions are well-studied when the hardening conditions of cementitious materials are optimum. Therefore, the main objective of this research was to study t...

To promote the efficiency of waste heat recovery from granulated blast furnace (BF) slag, a novel method catalyst-enhanced steam reforming bio-oil to recover slag is proposed. CaO utilized as superior catalyst for process reforming. The thermodynamic production in BF obtained using HSC 6.0 software. optimal conditions are mainly assessed according hydrogen yield, concentration and carbon produc...

Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) ...
