There are significant volumes of by-product materials such as ground granulated blastfurnace slag (GGBS) and fly ash that can act as part of the cementitious binder in concrete and masonry. There is also the opportunity to incorporate secondary aggregates, by-products from other processes, into masonry.
The recycled content for aircrete and aggregate blocks is approximately 31 per cent.
The blocks sector use of secondary aggregates and cement represents over 20 per cent of total tonnage. The aerated blocks sector use of secondary aggregates and cement is equivalent to over 70 per cent of total tonnage, as almost all aggregates used by the aerated sector is fly ash.

Meeting Building Regulations is not enough to minimise fire risk. Regulations do not cover property safety nor construction stage. Construction stage fire safety is the remit of the HSE.
The HSE say: “All those making design and procurement decisions that significantly affect fire risk should consider and reduce the risk and consequences of fire during the construction phase through DESIGN.” (HSE emphasis).
To do this, choose non combustible materials: choose precast and masonry. Read more.
