THE USAGE OF THE CONCRETE WASTE FOR THE SECOND TIME. ^{[№ 4 ' 2001]}
It is considered a question about possible utilization of the concrete and ferro-concrete goods, the main trends of the usage the products of crush for the second time. The usage of broken bricks secondaly with heavy concrete reduces its cost price considerably. It is possible to use small fraction as a silica component in the cell's concretes. There are shown the results of the experiments and its analyses in the article.

THE MAGNETIC-ACTIVATED WATER IN THE BUILDING TECHNOLOGIES ^{[№ 1 ' 2001]}
The question about using. The magnetic-activated water for hardening the concrete mixtures is discussed in this article. The authors open the reasons of a low industrial need for these high- effective technologies and show the ways, which allow to use the magnetic activation of water for hardening concretes. It allows to approve technical and servicing parameters of wares and economize about 10-15% of cement. The article shows the experimentTs results, nhich were carried ont by the authors on more then 150 experimental cubs.
