Abstract

The present invention provides a method for producing a synthetic mineral polymer brick comprising the steps: forming a die, of which cavity cross-section is the same as the cross-section of the brick to be produced, and two compressing rods, which can move opposite to each other; metering batch of cement, silic mineral, water and polymer binding additives; uniformly blending and providing the humidity for the batch to form a semidry batch; feeding the semidry batch into the die cavity; displacing a first compressing rod in a first direction to press the fed semidry batch in the die; displacing a second rod in a second direction to press the fed semidry batch in the die to form a pre-shaped brick in the die; displacing the first compressing rod in the second direction to be drawn out of the die; nextly displacing the second rod in the second direction to push and bring the pre-shaped brick out of the die; and displacing the second rod in the first direction to return to the original position that is available for the next cycle.

Abstract

A synthetic mineral polymer bricks are provided comprising the following components: sand, cement and polymer additives which are metered in a form of a batch and are formed by molding method, the metered batch is compactly pressed whereby to provide the bricks in uniform sizes, weights and strengths, wherein the batch components (% by weight) of the brick comprising: sand: 77% - 64,75%; cement: 20% - 35%; and polymer additives: 0,25% - 3%.
