Capsules (2) for reinforcing fibrous concrete and comprising the individual fibers (1) formed as coiled elements and the solid wrappers (4) made of ice. The method of the production of the capsules with reinforcing fibers consists in that first the individual fibers are prepared as coiled elements whereupon each individually coiled fiber is enclosed in the wrapper made of a water droplet and the capsule formed in this way is then rapidly frozen, preferably by means of the action of liquid nitrogen having the temperature of -196°C. The method of the production of the reinforced fibrous concrete consists in that the capsules prepared in the aforesaid way are dispensed into the concrete mixture.
摘要:
A coated particle having a shimmering appearance to an observer contains a refractive particle, a transparent coating on the refractive particle, reflective particles and refractive particles embedded in the coating, with one of the reflective particles or the reflective particles primarily at a surface of the coating. Also an engineered stone has a shimmering appearance due to incorporation of coated particles.

The present invention provides a method for producing a construction element which comprises partially curing an amount of vegetable oil, mixing said partially cured vegetable oil with an aggregate and then further curing said vegetable oil within said mixture. There is further provided a structural element comprising at least partially cured vegetable oil and an aggregate. A composition for use in the production of a reinforced construction element is provided, said composition comprising a vegetable oil, a graded aggregate and a fibrous reinforcing agent. Construction elements produced using the composition are described. A method for producing a reinforced construction element comprises mixing vegetable oil with a graded aggregate, mixing a fibrous reinforcing agent with said mixture of vegetable oil and aggregate, and then curing said vegetable oil within said mixture of vegetable oil, graded aggregate and fibrous reinforcing agent.

摘要:
Specially designed to form a high capacity barrier for radioprotection in the X-ray range, a mass for producing mortar, bricks, blocks or tiles, involving the incorporation of cement, aggregate, water and chemical additives varying in accordance with the features that may be required for this mass, such as strength, setting time and others, the invention focuses its characteristics on the fact that, as an aggregate barite plays a part in it in a suitable proportion according to the increase in the general density of the mass to be obtained, a highly continuous grain size being envisaged for said barite as well as a system of differential vibrating, except in the case of the mortar, with a view to obtaining optimal consistency in the mass.
