This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight also lowers material and transportation costs. The slabs are typically 120 cm wide with standard thicknesses normally between 15 cm and 50 cm. Reinforcing steel wire rope provides bending resistance.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material. It is eco-friendly, and suitable for producing concrete-like blocks . [ 1 ] It is composed of quartz sand , calcined gypsum , lime , portland cement , water, and aluminium powder .
New polished concrete slab. The mix design of the concrete should be 3500 psi or higher. The concrete should be poured full depth to take advantage of the concrete's full structural strength, and also help to prevent cracks. The concrete should always be professionally finished with power trowels and cured with water for seven days. Polishing ...

Concrete floors were found in the royal palace of Tiryns, Greece, which dates roughly to 1400 to 1200 BC. [11] [12] Lime mortars were used in Greece, such as in Crete and Cyprus, in 800 BC. The Assyrian Jerwan Aqueduct (688 BC) made use of waterproof concrete. [13] Concrete was used for construction in many ancient structures. [14]

The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.
