Concrete is a major component in every construction project. The use of precast concrete technology has been embraced by the construction industry in Ghana. This study seeks to analyze cost estimating of the structural frame (column and slab) by considering castinplace and precast concrete slabs and columns, respectively.
In heavier tools, this is a secondary option for breaking up concrete rather than drilling through it. In lighter tools, this mode can be pivotal for accelerated chiseling and chipping. While this is by no means an exhaustive list of the wide array of concrete tools, it should help to address the basics when making your next concrete tool purchase.
