A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.

Described herein is an acoustic structural panel having a first exposed major surface opposite a second exposed major surface and side surfaces extending between the first and second exposed major surfaces, the acoustic structural panel comprising a first protective layer comprising at least a portion of the first exposed major surface, a second protective layer comprising at least a portion of the second exposed surface, a core structure located between the first and second protective layers, the core structure comprising, a foam body; and a fibrous body, wherein the first major exposed surface of the acoustic structural panel comprises a plurality of apertures exposing the fibrous body.

An improved insulating block that offers great structural strength by having an interconnected block material structure with cavities filled with insulating material. The paths from the front face to the back face of the block through the block material are adapted to ensure an improved thermal insulation of the block, while providing a high load bearing capacity and allowing continuation of longitudinal reinforcement. This results in a block that can be easily manipulated and handled. Furthermore, the invention provides a method of manufacturing and a use of said blocks, and a wall or structure of said blocks.

Lightweight masonry hollow bricks of a substantially rectangular cuboid shape having central cavities and side indentations. A concrete composition of the masonry hollow bricks includes cement, water, sand, a coarse aggregate, and an insulating material, e.g. perlite, polyethylene, crumb rubber. The developed masonry hollow bricks met the ASTM requirements for non-load bearing masonry bricks in addition to satisfying the ASTM standard as being lightweight masonry bricks.

A building block and a building system used for construction a building are disclosed in the present invention. The building block includes: an inner face, an outer face, an upper face having a base face and a projection protruding upward from the base face, wherein the projection extending longitudinally for the entire length of the upper face; a lower face having a complementary groove for interlocking with the projection of a cooperating interengaging building block; a first end; a second end; each of the first end and the second end has a header face, which is substantially one of a planar face, a male header face and a female header face, the male header face of the building block interlocking with the female header face of a cooperating interengaging building block; the cooperating interengaging building block is substantially similar to the building block.

A retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

A masonry block system that includes a stretcher block and a half block, each block having connector means for interlocking with an adjacent block, the blocks being constructed in a such a manner as to enable quick and easy assembly of a building structure.
