Green Composites in Architecture and Building Material Science

Abstract

Currently, the topic of improvement of man`s live ability is becoming increasingly important. The notion of luxury living in the city includes social comfort, environment comfort (urban, natural landscape component). A wide range of small architectural forms of different architectural design and purpose is developed. The basic material for the production of small architectural forms is concrete. On optimal combination of negative and positive qualities, concrete is the most cost-effective material. In order to avoid increasing the price of hardscape, at their creating, it`s actual to use local raw materials and industrial waste. On their basis the modern high quality building materials are developed. To reduce prime costs of construction materials the technogenic raw materials are used. The solution of this actual problem possibly on the basis of expansion of a source of raw materials of the stone materials suitable for production of filler. Use of fine-grained concrete is perspective. This look allows to receive high-quality structure of a material, differs high technological effectiveness, allowing it is rather simple to make products as a pressing method with immediate striking, and it is easily and effectively modified by a molding method that is especially convenient for monolithic housing construction, and, besides, by means of organic-mineral modifiers, providing materials with various use of cheap local sand that allows to reduce concrete cost by 15-20% in comparison with coarse-grained concrete on rubble.

Perspectives of application of aerated concrete for 3D building printing

“…The efficacy of their implementation is proved and obvious for a wide range of tasks [15][16][17][18][19][20]. As an active component, the plain portlandcement CEM I 42.5N was implemented, which contained C3A of 4%.…”

Composite Binder for Structural Cellular Concrete

“…The composite binder can be obtained by main components mixed or separate grinding. At the same time the maximum possible number of ingredients (taking into account the compatibility factor) should be added during binder preparation [13][14][15]. Such approach:…”

Technology of small architectural forms for the improvement of rural settlements

“…In addition, a specific feature of SAF is their complex geometric shape and small size, which complicates the use of traditional methods of manufacturing products based on concrete mixtures with a large aggregate. To meet all of the above requirements, it is rational to organize the production of SAF from fine-grained selfcompacting concrete using vibration-free technology [1,2].…”
