An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

An elongate shaped abrasive particle comprises an elongate shaped ceramic body having opposed first and second ends joined to each other by at least two longitudinal sidewalls. At least one of the at least two longitudinal sidewalls is concave along its length. At least one of the first and second ends is a fractured surface. Methods of making elongate shaped abrasive particles and abrasive articles including them are also disclosed.

Apparatuses and methods associated with creating a form to construct a concrete structure (e.g., a concrete building). In embodiments, an apparatus may comprise a number of forming system components, including but are not limited to a plurality of fixed or adjustable posts; a plurality of fixed or adjustable roof struts, a plurality of fixed or extensible frames; and/or a plurality of mounts. The fixed/adjustable posts, the fixed/adjustable roof struts, and the fixed/extensible frames are selectively and adjustably coupled together to create a form of selected dimensions to construct the concrete structure/building on site with reduced number of pours, e.g., a single pour. Other embodiments may be disclosed or claimed.

A mold assembly for forming concrete products comprising a mold box having cavities for receiving and molding concrete products and a mounting bracket extension coupled to each side wall of the mold box and forming a lower mounting surface of the mold box. Die alignment holes are formed in an underside of each mounting bracket extension and are configured to receive alignment dowels extending upward from shelves of the concrete products forming machine on which the mold box sits. The mounting bracket extensions further include mold transfer locators formed on the underside inward of the die alignment holes so that they are exposed from below when the mold assembly sits on the shelves of the concrete products forming machine. These locators are configured to locate the mold assembly onto mold extractor arms when the mold assembly is lifted off of the alignment dowels by the mold extractor arms during a mold extraction process.
