The Sand to Mortar Ratio to Lay Concrete Blocks Hunker
For laying concrete blocks, you generally want a thick, creamy mixture that will stick but also provide an adequate base for the blocks' weight. Water Always add water sparingly to your mortar mix as you are mixing it up, because too much will make it difficult for the sand particles to bond with the binding agent in the concrete, which is cement.
