This paper presents studies on the possibility of utilization technogenic waste from metallurgical industry by method complex processing in order to reduce anthropogenic load environment region with example zinc silicate-magnetite-carbon system. The selected sample clinker dump welting was subjected chemical and scanning electron microscopic analyses thermodynamic modeling. Thermodynamic were carried out temperature range 1600-2200 K pressure p = 0.1 MPa, modeling process electric melting an...
In the article questions of application a steel fiber for disperse reinforcing fine-grained concrete are considered. Main filler mix was KMA industrial sand enriched with sand. The carried-out researches showed advantage wave before anchor and flat milled. optimal type is revealed, in which greatest increase strength deformation characteristics observed. Thus, it can be concluded that its shape have significant impact on length building structures buildings as whole.
In the article questions of application mining waste: dropout quartzite sandstone crushing as filler in fibre concrete production were considered. Composite binders based on cement and also developed. The effectiveness composite binders’ usage consisting improving physical mechanical characteristics reduction their prime cost compared to with a slight increase complexity was proved. compositions dispersed reinforced steel wave fiber without it efficiency use reinforcement fine-grained is...
The necessary fiber content in the first place is determined by requirements of bending strength and resistance to dynamic loads. depends on composition consistency concrete, properties mixing techniques. most widespread types fibers, their advantages disadvantages, possible areas application are considered. Fibers whose modulus elasticity greater than a concrete matrix, such as steel fibers or glass increase workload cracks.
Acute questions of steelfiber using for disperse-reinforced fine-grained concrete are considered in the article. Researchers patterns held. The efficiency crushing dropout quartzitic sandstone is proven. article studies physical and mechanical characteristics filler. chemical composition binder presented. For dispersed reinforcement fine influence steel fibre on strength mixture was studied. fiber technology obtaining a fiber-concrete Studies showed effectiveness with percentage 3%...
Fine-grained fiber concrete used in 3D printing is significantly different from conventional heavy concrete, which determined by the increased consumption of cement, low water-cement ratio and absence large aggregates. The largest grain size fine aggregate selected taking into account thickness section, frequency type reinforcement, as well method placement. Despite fact that tensile strength on sand more than 1.5 times higher coarse sand, while there a decrease compressive strength. Due to...
The question of adhesion fibers with a cement matrix is considered. Under certain conditions the connect and hold places potential breaks. important characteristics fibre are: surface texture, cross-sectional shape construction in longitudinal direction fiber. A sufficient number located acting force can take tensile after rupture matrix. fiber content percentage volume, which to increase strength, properties finished concrete mixture depend on parameters. As rule, there poor smooth steel stone.
The effectiveness of silica fume for the fine-grained concrete used 3-D technologies is proved in give scientific paper. advantages using concretes are presented. mathematical modeling high-quality compositions’ development. has been by studies. increase strength characteristics with addition explained active pozzolan reaction, which starts when mix mixed water.
A promising method of obtaining mineral fiber fillers for dry building mixtures is the processing waste that comes from production technogenic fibrous materials (TFM). The novelty work lies in fact that, first time, basalt wastes were studied not only as reinforcing components, but also binder ones involved concrete structure formation. purpose article to study physical and mechanical properties additives optimizing composition raw mixes. To assess possibility using complex TFM ground 5 10...
The article proves the efficiency of construction-based use fibre concrete. technique high-quality fine-grained concrete creation is presented. chemical composition binder was studied and physical mechanical characteristics filler were revealed. 2 types steel fibers studied: anchor in form a fir-tree. conducted studies proved effectiveness dispersed reinforcement with fiber. It established, that usage fiber fir-tree greatest increase operational reached.
The article deals with the application of combined reinforcement fi-ne-grained concrete steel wave and polypropylene fibers. High-density packaging mixture components was used to improve strength deformation characteristics. In order reduce cost fibre concrete, composite binders were developed. Rational selection filler use a fiber gave opportunity get tensile compressive – 84.8 MPa, in bending 19.8 MPa on technogenic sands Kursk Magnetic Anomaly. With by magnetic anomaly 82.8 19.1 same...
In the article use of technogenic raw materials (dropout quartzite sandstone crushing) as filler for concrete is considered. Methods research by leading scientists Russia are given. The physical and mechanical characteristics such as: size modulus, bulk density, real voidness, water demand, cement Studies prove possibility effective droupout crushing fibre concrete.
The current stage of development building materials science is characterized by the widespread use dispersed reinforcement various compositions and sizes in mortars concretes. In paper, priority scientific technical directions for rational reinforcing fibers, including secondary ones, was established effective resource energy-saving technologies production competitive commercial products construction industry. A study phase formation concrete using technogenic fibrous carried out. Using...
Lime materials are in great demand for the restoration of walls historical buildings. However, lime coatings have insufficient resistance during operation. The purpose this work was modification mortars with silicic acid sol order to obtain more durable crystalline construction purposes. A technology has been developed obtaining a silica-containing additive, which consists passing liquid glass solution density 1.053 kg/m3 through cationic column and pH 3-4 charge (-) 0.053 V. regeneration...
Numerical modelling can simulate the interaction between structural elements and soil continuum in a piled-raft foundation. The present work utilized two-dimensional finite element Plaxis 2D software to investigate settlement, swelling, behavior of foundations during settlement swelling on various profiles under load combinations geometry conditions. field laboratory testing have been performed determine parameters necessary for numerical modelling. Mohr–Coulomb model is soil, as this...
Waste is available in an abundant form and goes to landfill without any use, creating threats the environment. Recent past studies have used different types of waste stabilize soil reduce environmental impacts. However, there a lack on combined use marble dust, rice-husk ash, saw dust expansive shale soil. The current study tries overcome such gap literature, studying effect shale's compaction characteristics permeability properties. According unified classification AAHTO system,...
