Precast concrete

Precast concrete is a construction product produced by casting concrete in a reusable mold or “form” which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific 
forms and cured on site. Precast stone is distinguished from precast concrete by using a fine aggregate in the mixture, so the final product approaches the appearance of naturally occurring rock or stone.more from vmeprecast | nms

Hollow-Core Slabs

hollow core slab, also known as a voided slabhollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment buildings.Cores are typically either circular or elliptical. Slabs may be reinforced or prestressed and are designed as ribbed slabs. The hollow cores afford a reduction in self weight of 30% or more, compared with a solid slab of the same depth. For most applications, no propping is necessary during construction, but crane access is essential. An erection rate of up to 600 m² per day is possible.Size of hollow core slab

Prestressed hollow core slabs are manufactured  generally in units 1200 mm wide with depths of 120,150, 200 and 250 mm. Units are made to order in lengths up to 12 m. The number and disposition of prestressing tendons varies according to span and loading.

Precast columns and beams

Pre-stressed RCC supporting precast column and beam are advantageous for fast constructions as no propping of beams are required, there is no need for expensive on-site formwork and flexibility with design is also possible. Precast columns and beams can be used for building any structure including bridges.The main advantage of a composite beam structure is that it permits less structural depth for a given load-bearing capacity. Precast beams and columns are manufactured in a variety of sizes, shapes and lengths. The concrete surface is smooth and the edges are chamfered. read more


By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. Utilizing a Precast Concrete system offers many potential advantages over site casting of concrete. The production process for Precast Concrete is performed on ground level, which helps with safety throughout a project. There is a greater control of the quality of materials and workmanship in a precast plant rather than

 on a construction site. Financially, the forms used in a precast plant may be reused hundreds to thousands of times before they have to be replaced, which allow cost of form work per unit to be lower than for site-cast production.
