Abstract: A system and method for light steel frame construction which utilizes a single type of material for panels and fill to produce an affordable, thermally efficient, strong and durable building. The system and method for light steel frame construction generally includes a light steel frame to which is secured a plurality of outer block panels and inner block panels via fasteners. Each of the block panels is made of a porous concrete mix which is pre-cured and cut to form the rectangular panels. Gaps between the outer and inner block panels is filled with a fill material, the fill material being formed of a dry mix porous concrete which is mixed with water on-site and pumped into the gaps before being allowed to expand and cure. Adhesive materials may be applied to the panels to fill gaps and secure the panels to each other.
