The weight of a concrete slab of dimensions 500mm x 500mm x 25mm will be 33 pounds, if you do your calculations correctly as respecting this volume 6250000 cubic mm of the concrete.

The weigth of concrete will be the sum of the individual weights: 3 + 6 + 12 + 2 = 23 kg and even if a part of the water evaporates, you can expect the weight to be about 22 kg.
Unless it is going to be well supported and see only compressive stress, you should put some reinforcement (steel bars) also in the concrete.

Calculate the volume of cured concrete in English system (cubic feet) and multiply with density 150 ,y will get the weight.
