What is the best kind of cement or concrete I should use? Also, cement or concrete that will not crack.
whoever you get to pour it will know what to order...i would order a 4000 lb. mix with fiber...since you are doing a basement floor , freezing and thawing wont be an issue...
you are thinking of concrete....Concrete is cement plus aggregate [small rocks], which gives it strength. And ALL concrete and cement will eventually crack, but you can prolong it by adding proper reinforcement such as steel re-bars, wire 6x6 mesh, and glass strand fibers in your concrete.
