Performance of Concrete Floor Slabs Using Different Concrete Mixes

: The quality of a concrete floor or slab is highly dependent on achieving a hard and durable surface that is flat, relatively free of cracks, and at the proper grade and elevation. The objective of this study is to investigate the performance of different concrete mixes containing “Nano clay, Basalt and Dry shake”. To achieve the main aim, an experimental program consisted of fabricating and testing concrete slab 3x3 m2 with thickness 15 cm divided into four quarters, each quarter had a specific concrete mix proportions (Nano clay, Basalt, Dry shake and control). The laboratory tests used included compressive strength, abrasion resistance and Pull off resistance. The results showed that Basalt concrete mix had low water absorption, high abrasion resistance and high compressive strength and Pull off strength as compared to control concrete mix and almost follow it Dry shake mix and Nano clay mix in their performance. In conclusion, the studied concrete mixes had favorable performance and properties compared to the control mix and the most beneficial results was recorded in Basalt mix.
