ABSTRACT:
An ultra light weight insulating building block is manufactured from an aggregated particulate formed by mixing expanded perlite together with cement in the proportions of approximately 24 parts of perlite for each part of cement by volume and thereafter adding a minimum amount of potable water to agglomerate the contents until the mixture is tacky. The mixture is thereafter cured in air to form the agglomerated particulate which may thereafter be used together with cementious material to manufacture the building blocks. The cementious material may be cement or a mixture of cement, fly ash and an air entrainer.
