“…Organic compounds influence only rheological properties of cement mixtures, when fine mineral additives improve rheological, structure-mechanical and functional E3S Web of Conferences 258, 09089 (2021) UESF-2021 https://doi.org/10.1051/e3sconf/202125809089 characteristics of SCC, making the process of flowing into the heavily reinforced formworks easy. Combination of mineral additives with organic superplasticizers and reasonable aggregate grain size distribution gives high-strength SCC (not less than 70 mPa) [13,14].…”

Modern Materials science in Сonstruction is developing in a way of higher functionality, durability, ecological safety of the materials, which also must be easy to work with. The workability of concrete is provided by its property to fill the formwork under the influence of gravity. Small architectural forms (SAF) – are practical and art objects which complement outdoor spaces and enrich architectural, urban and landscape composition of the city. Manufacturing of SAF is complicated by its extraordinary geometric shapes with plenty of tiny elements. This fact limits the usage of traditional technologies of vibration for compaction. In this paper properties and composition of self-compacting concrete (SCC) are discussed, as well as the possibility of its application for thin-walled heavily reinforced constructions to produce unique SAF for landscape design. The obtaining of flowable segregation-resistant concrete mix with low water-cement ratio is studied. The hypothesis of applicability of SCC for SAF in landscape design is based on high deformability, flowability and consolidation by means of its own weight without segregation. The methodology of the research is based on the literature review concerning the usage of SCC for SAF with some special additives with plasticizing and anti-segregating affects. The investigation showed that SCC is applicable for SAF in landscape design.

“…A porous space of the cement stone contains gel pores with the cross section of up to 10 nm, the microcapillaries of 0.1 to 1µm and noncapillary pores of more than 1 µm [10][11][12]. Double electric layers (DEL) [13] are formed on the walls of those pores and capillaries at the phase interfaces that consist of 75 % of calcium hydrosilicate [10] with negative potential-defining ions and the Са 2+ ion concentration in these DELs in particular of counter ions is one order of magnitude higher than that in the solution volume.…”

Theoretical and experimental investigations of the influence of concrete moisture, its age, holding conditions after its thermal moisture treatment and other factors on the specific electric resistance of the concrete of a C32/40 grade used for reinforced concrete sleepers have been carried out. The obtained research data allowed us to specify holding modes and the duration of them and these enable the generation of objective information on the specific electric resistance of the concrete used for the sleepers during their operation.

“…These additives were called dewatering (water reducing) additives because of their ability to reduce mixing rate. By using these additives, it becomes possible to reduce water-cement ratio to 40-45 % while maintaining the necessary mobility [2][3][4][5][6]. These materials are classified as surfactant-active substances (surfactants) [7].…”

Abstract. The main aim of this research is the investigation of effect of the composite additive (a mixture of hyperplasticizer and microsilica) CM 02-10 (10 % of MS and 0.2 % of HP) on strength characteristics of concrete. Interaction of concrete with plasticizing and siliceous additives individually depending on their percentage content by the weight of cement is also investigated. Results of experiments with such additives on the fluidity of concrete mix and strength of concrete are presented. Additives used in the experiment: superplasticizer S-3, fused microsilica FMS-85, hyperplasticizer PENTAFLOW AC 2, and composite additive CM 02-10. In this paper results of tests of samples aged 3, 7 and 28 days are presented.
