Light-weight concretes on phytogenesis organic aggregates. Specifications

2Scope / Description

This standard applies to lightweight concrete made with cement as the binder, plant-based organic fillers (such as sawdust, wood chips, hemp stalks, flax stalks, cotton stalks, rice straw, etc.), and chemical admixtures (hereinafter referred to as arbolit). The standard specifies the technical requirements for arbolit mixtures, hardened arbolit mixtures (arbolit), and their preparation materials, as well as acceptance rules and test methods. Arbolit is used for insulation layers in floors, roofs, and cladding, as well as for precast, precast-cast-in-place, and cast-in-place reinforced concrete structures for various purposes, buildings with an indoor relative humidity not exceeding 75% and free from corrosive gases, and as non-removable formwork in the construction of buildings and structures for various purposes, including low-rise buildings. The use of arbolit is permitted in livestock, poultry, and fur-bearing animal buildings with a relative humidity exceeding 75%, provided that the inner surfaces of these structures have a moisture barrier, which should be specified in the working drawings. The outer surfaces of arbolit enclosures in contact with atmospheric moisture, regardless of indoor humidity conditions, should have a protective layer to protect them from moisture, complying with current building codes and regulations. Recommended application areas for Arbolit are listed in Appendix A. Standards and technical specifications for specific types of Arbolit products and structures should be developed with reference to the requirements of this standard. Note: The design and calculation of Arbolit structures should comply with [1].
