BENEFICIATION Hollow-core slabs being installed at a housing project in Polokwane. two truck-and-trailer configurations. With a combined weight of 44t, the hollow core slabs were placed in just more than four hours using a knuckle-boom crane that was easily positioned next to the structure. The scope of supply also included two flights of precast concrete stairs, which allowed for further time savings on the project. This approach also provided the building teams with a safer and more efficient means of accessing the second level. Located outside the CBD, the factory is the heart of the operation, and this is where the company’s team also assists its clients, including architects and structural engineers, optimise the use of hollow-core slabs. A sound example is the use of the construction material to create stunning cantilevered balconies and outside entertainment areas, transcending the limitations of in situ construction techniques. Hollow-core elements are manufactured according to SABS standards using cutting- edge technologies, including English Spiroll machines. The factory features specialised 28 _ QUARRY SA | MAY/JUNE 2018 forms and moulds that guarantee accurate casting, a prerequisite for these projects. A separate steel-fixing yard also facilitates accuracy and therefore a high-quality reinforcing in the concrete casing. Sensors constantly monitor the temperature and moisture content of the concrete mix and CoreSlab only sources its raw materials from long-standing supply partners.
