Abstract
A prefabricated monolithic slab (PMS) has a number of valuable advantages, they allow to significantly decrease the weight of construction keeping the necessary structural-load capacity, to speed up and cheapen work conduction, to increase the heat isolating properties of an enclosure structure [1]. In order to create a design method of prefabricated monolithic slab fire-resistance, it's necessary to perform a series of PMS testing, one of which is being described in this article. Subjected to the test is a fragment of prefabricated monolithic slab with polystyrene concrete inserts along the beams with bent metal profile 250 mm thick, with a 2.7 m span loaded with evenly spread load equal to 600 kg/m2. After 3 hour testing for fire-resistance [2] no signs of construction ultimate behavior were detected.
Highlights
The prefabricated monolithic slab (PMS) is a new cost-efficient construction type
A ceramic brick has 10.0, claydite - 20.0. This means that by expanding the use of PMS aggregated with aerated concrete, the share of environmentally friendly building designs can be significantly increased in total number [4,5,6]

Summary
The prefabricated monolithic slab (PMS) is a new cost-efficient construction type. Prefabricated monolithic slab allows to significantly decrease a construction weight keeping the necessary structural-load capacity of the construction, to speed up and cheapen work conductions, to increase the heat isolating properties of an enclosure structure [3]. According to the Ministry of Environment of Finland, cellular concrete belongs to the best class of environmental safety. A ceramic brick has 10.0, claydite - 20.0 This means that by expanding the use of PMS aggregated with aerated concrete, the share of environmentally friendly building designs can be significantly increased in total number [4,5,6]. In European countries civil and structural reinforced concrete building engineering, as well as construction fireproof analysis are held in accordance with EN 1992:EUROCODE 2 [8]. In the Russian Federation reinforced concrete building designs under fire conditions are held in accordance with STO 36554501-006-2006 [9] which does not subject the prefabricated monolithic slab.
