Abstract:
1. A room comprising: at least four freestanding walls; each of the four freestanding walls consisting of: at least one of a block; at least one of a semi-block; at least one of a lintel beam; and at least one of a head beam; wherein the at least one block, the at least one semi-block, the at least one lintel beam, and the at least one head beam are made of a material consisting of Portland cement, sand, water, and steel fibers; wherein the at least one block consists of: a base having a top end, a bottom end, two separate cavities symmetrically placed inside the base, and hollow protrusions extending over the top end of the block, wherein the cavities run from the top end to the bottom end of the base; and each hollow protrusion is connected to one of the cavities; each cavity includes: a first segment located near the bottom end of the base having a square shape with a first longitudinal dimension; a second segment connected to the first segment, the second segment having a square base with a second longitudinal dimension; the first longitudinal dimension is greater than the second longitudinal dimension; and a step formed at a point where the first segment connects with the second segment; wherein the at least one block, the at least one semi-block, the at least one lintel beam, and the at least one head beam in a compression test are capable of sustaining a load of 16 tons; wherein each one of the at least one block, the at least one semi-block, the at least one lintel beam, and the at least one head beam is a pressure molding block formed without any heat treatment; wherein the at least one block, the at least one semi-block, the at least one lintel beam, and the at least one head interconnect to each other; wherein walls are formed by connecting successive layers of the at least one block, the at least one semi-block, the at least one head-block, and the at least one lintel beam, by said protrusions and first segment, one next to the other or one over the other; and wherein the at least one block, the at least one semi-block, the at least one head-block, and the at least one lintel beam connect to each other free of an external structural support, plaster, an internal structural support, an adhesive, a mortar mixture, and support beams.
