The “ARMO” ashlars are manufactured with concrete in measures of 12x20x40 cm. the geometrical designs of the block allow them to be assembled together like jig-saw puzzle without the need of cement-sand mixture or any binder. This innovation in concrete blocks can reduce the construction time (up to 50%) and direct cost (up to 25%). The Block ARMO system allows builders to create concrete structures that are as strong as any other, but it reduces total building time by as much as 50 percent. Funded by the Mexican Council for Science and Technology, the single-module blocks can be assembled without any binders or mixtures. The only additions on top of the blocks themselves are metal rods that get inserted into the blocks’ holes every 80 centimeters.
