Aggregate Industries provides solution for additional apartment floor mid-build

Aggregate Industries’ Lytacrete solution was chosen to help Wright Investments introduce an additional floor mid-construction at a new seven story upmarket apartment scheme in Southampton.

The apartment block, on Albert Road South, Southampton, was originally designed as a six story building but part-way through construction, plans were re-designed to include an extra floor.

The new floor needed to be added without overloading the existing structure already in place. Aggregate Industries made this possible with Lytacrete – a specialist lightweight solution – in place of conventional weighty concrete.

420m3 of Lytacrete was supplied for the completion of 7 storeys in the Albert Road South apartment scheme, due for completion in 2018.

Lytacrete concrete is formed using Lytag secondary aggregate and can be up to 50% lighter than traditional comparable materials.

Lytag secondary aggregate is made using innovative technology which transforms fly ash into small pellets which are then heated to 1,100°C. The pellets formed are rounded in shape and range in size from 14mm down to fines and can be used as a superior, consistent, lightweight aggregate.

Lytacrete will reduce the load of the construction by approximately 7620kN over normal weight concrete whilst maintaining its structural integrity. It has also enabled reduced size columns, beams and slabs, allowing greater room for the developers to add the additional floor.

Steve Curley from Aggregate Industries comments: “The use of Lytacrete eliminated the need for expensive re-structuring works to support an additional floor, which most importantly helped keep the project to budget and schedule.”
