Granulated Blast Furnace Slag an overview

Granulated phosphorus slag is a latent cementitious material but less reactive than granulated blast-furnace slag at early age due to the lower Al 2 O 3 content and the presence of P 2 O 5 and F. A hydraulic index of phosphorus slag is defined as follows (Shi et al., 2006; RCT 5024-83, 1983):

Granulated Slag

Granulated Blast Furnace Slag is a cement substitute that improves durability and also the environmental credentials of concrete mixes. It is a by-product of the iron-making industry. For every tonne of GBS used in a concrete mix, the embodied CO2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement.

Ground Granulated Blast Furnace Slag an overview

Slag. Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the

Oct 01, 2016 The use of slag aggregates from iron and steel production in construction dates back to the Romans who used crushed slag from the crude iron production of that time to build their roads. Slag is particularly useful as an aggregate, due to the high mechanical resistance of the slag grains which exceeds those of many natural aggregates.
