The MAYA project (Figure) is a new concrete armour block (single layer) proposed by the University of Salerno (PATENT PENDING RM2015A000052 - PCT/IB2016/050641), from authors Fabio Dentale, Luigi Pratola, Eugenio Pugliese Carratelli and Felice Antonio Petrillo.

To overcome the drawbacks of the current concrete blocks, the project's slogan is "Easy to make, Easy to place".

Easy to make: the formwork is made through superimposition in an ordered sequence of a plurality of square layers (six layers). The six square layers may be made by using simple and inexpensive manufacturing technologies. By way of example, the square layers may be made of styrofoam or polystyrene, and the four side square panels may be optionally made of wood. The materials which are used contribute to the reduction of costs for manufacturing and handling the artificial units.
Easy to place: the artificial unit allows the installation operations to be carried out without requiring specialised personnel or high-tech instrumentation, achieving interlocking independent from the mutual placement of the units, favouring a random, not induced, arrangement, achieving what is defined as mutual automatic interlocking. This further entails that the positioning operations are faster and simpler, whereby it is possible to reduce the construction time and, consequentially, the costs in terms of equipment, personnel and operative phases for making the work. From the structural point of view, the particular configuration of the shape and easy installation permits the artificial units to be arranged in an optimal manner, even in relation to the conditions of engagement, preventing the contiguous faces from coupling to each other, which is different from what occurs, for instance, for cubes. In this way, independently from the specific position of the single units constituting the layer, it is always guaranteed a proper roughness and porosity (Figure).
