A interlocking modular block system for structure assembly includes a solid prestressed concrete post having a square cross-sectional shape, a first hollow cuboid shaped block having a triangular cutout on each of its two opposing sides, a second hollow cuboid shaped block having the triangular cutouts on each of its two opposing sides, a first hollow cubic shaped block with a triangular prism shaped protrusion on each of three consecutive walls, configured to join three walls, a second hollow cubic shaped block with a triangular prism shaped protrusion on each of two opposing walls, configured to join two colinear walls, a third hollow cubic shaped block with a triangular prism shaped protrusion on one wall, configured to terminate a wall, and, a fourth hollow cubic shaped block with a triangular prism shaped protrusion on each of two consecutive walls, configured to join two perpendicular walls.

A molding equipment and method to mold stackable inter-engaging bricks, blocks, stones and the like and bricks, blocks, stones and the like produced therewith are disclosed. The molding equipment comprises a main structure which contains individual cavities. Each cavity preferably has a middle structure to which a brick separating element can be attached. Without the brick separating element, each cavity can form two attached splittable bricks whereas with the brick separating element attached, each cavity can hold two individual smooth or embossed face bricks. The size and shape of the stackable inter-engaging bricks is such that once out of the mold but still in an uncured form, the brick can stand on its side without falling down, being damaged, buckling or being otherwise deformed during the manufacturing process.

A brick includes outer walls defining a hollow interior space, the outer walls including: substantially flat top and bottom walls; and side walls angled inwards toward a central portion of the NPR brick, such that application of a compressive force between the top and bottom walls causes a lateral dimension of the brick between opposite side walls to decrease. At least some of the outer walls of the brick include a material having a negative Poisson's ratio (NPR).

Disclosed is a radioprotective building block for building a wall that is able to form a screen to ionizing radiation. The radioprotective building block includes:a core made of at least one radioprotective material, anda shell enclosing said core and including at least one shell part that is fitted around the core.

A block for decorating an outer wall or an inner wall in construction work and a construction method for bricklaying work, and more particularly, to a wall structure using blocks and frames each having a wedge-shaped coupling part formed therein and a method of constructing a wall using the same, wherein frames, which are integrally formed with beams, slabs, and pillars of a building to serve as a frame structure, are fixed and mounted, an isosceles triangular wedge-shaped concave groove or protrusion is formed on inner surfaces of the mounted frames, and blocks and intermediate blocks, in which an isosceles triangular wedge-shaped concave groove or protrusion is formed, are laid on the frames, thereby solving a disadvantage of bricklaying work in that it is vulnerable to horizontal vibration and improving seismic performance.

A wall constructed of building blocks designated as basic and modified, which have both convex and concave surface features. The convex and concave surface features are present both in the longitudinal and latitudinal direction. The convex and concave surface features are in parallel planes with one another. A curve in the wall is introduced with variation of these blocks with use of acute angle cutoff present on the latitudinal edge of the blocks. A curve in the wall can also be made with a bent on a block's longitudinal plane creating an obtuse angle at the outer longitudinal edge. The wall layers and ends are terminated by two types of filling blocks that are essentially one-half section of either the basic of modified block separated along the longitudinal direction or the latitudinal direction. The building blocks can also have a cavity used for filling in some compound.
