Expert work has been carried out to determine the causes of the low adhesion strength of hand-molded ceramic bricks with Maxpol colored masonry mortar. The tests were carried out in accordance with GOST 24992 on 6 series of samples aged 7 and 28 days of hardening. The adhesion strength in the series of tested samples at 7 days of age, which were washed with running water, is 54% higher compared to the samples that were not treated.The compressive strength of Maxpol colored masonry mortar meets the requirements of technical specifications 23.64.10-001-79211444-2017 . The adhesion strength in the masonry meets the requirements of technical specifications only in a series of hand-molded bricks that have been treated with running water at the age of 28 days.

In article basic provisions of the bill which is directed on improvement and simplification of the operating order of definition of a legal regime of use of lands by carrying out territorial zoning, and also an exception of institute of category of lands as a way of definition of the allowed use of the land plots are considered. Authors of the bill suggest to be schemes of territorial planning of subjects of the Russian Federation and municipalities the basis for territorial zoning. Delegation of power on zoning of territories with simultaneous cancellation of categories of lands to local governments and subjects of federation can lead to abuses on places and to lobbying of interests of limited number of persons. Such situation can be reflected in quality of the approved documentation and lead to inefficient administrative decisions in the sphere of land use. Proceeding from contents of agricultural regulations, carrying out land management and cartographical works, and for identification of especially valuable farmlands – soil, geobotanical and other researches which weren't carried out for decades will be required. Subjects of the Russian Federation in established periods will have to finance these works, they have no funds for these works. The most controversial issues and widely discussed in the Russian society are deprivation of lands of agricultural purpose of the special legal status directed on protection of lands and agrarian producers. The important concept in this question is, what principles of definition of lands on degree of efficiency will become fundamental. Bonitirovka of soils has to become a basis for such researches, and by no means cadastral cost. Use of results of a cadastral assessment reasonably for the taxation, pledge, insurance and other market and financial institutions. But quality of lands has not so much value terms, how many ecological and production value.
