“…According to the high frost resistant factor and high predicted cycles, compressive strength for these samples are increased after 200 cycles. Therefore, from the Kf factor, we can predict the performance of concrete in freezing-thawing [ 3 ]. The least frost resistant factors are obtained by CR5—1.55, CR10—2.16, CR20—2.18.…”

“…In this study, crumb rubber granulometry was done according to EN 933-1 (Figure 1), the air content of compacted fresh concrete was determined according to standard EN 12350-7, the slump according to standard EN 12350-2, the density of hardened concrete specimens according to standard EN 12390-6, the compressive strength of hardened concrete according to standard EN 12390-3, the flexural strength test was carried out according to EN 12390-5, and the freeze-thaw resistance according to standard LST L 1428.17. The porosity parameters of investigated concrete series were determined by measuring the kinetics of water absorption according to the previous procedure [3,27]. Fracture energy was calculated from CMOD (crack mouth opening displacement) curves [28].…”

“…Whitetopping construction is particularly suitable when the existing roadway structure is no longer enough due to high static and dynamic traffic loads. Usually, a milled layer will replace with prefabricated air burbles (which act as an air-entraining agent and will provide high resistance to freezing and thawing) ([ 3 ]), low shrinkage, polypropylene macro fiber-modified high-performance concrete to increase traffic areas’ load-bearing capacity. After milling, asphalt layer thickness should be at least 8 cm, and the thickness of the new cement concrete layer should not be less than 10 cm.…”

“…By continuing previous research [ 3 ] the main aim of this research work is to analyse the effect of crumb rubber used as fine elastic aggregate on the mechanical and durability properties of concrete and find the lowest amounts of rubber where concrete fulfills durability requirements but strength properties will not lose or will be similar compared to ordinary concrete for whitetopping structures. Also to get better strength properties rubberized concrete was modyfied by glass powder wastes.…”

This paper analyzes concrete fine aggregate (sand) modification by scrap tire rubber particles-fine crumb rubber (FCR) and coarse crumb rubber (CCR) of fraction 0/1mm. Such rubberized concrete to get better bonding properties were modified by car-boxylated styrene butadiene rubber (SBR) latex and to gain the strength were modified by glass waste. The following tests—slump test, fresh concrete density, fresh concrete air content, compressive strength, flexural strength, fracture energy, freezing-thawing, porosity parameter, and scanning electron microscope—were conducted for rubberized concretes. From experiments, we can see that fresh concrete properties decreased when crumb rubber content has increased. Mostly it is related to crumb rubber (CR) lower specific gravity nature and higher fineness compared with changed fine aggregate-sand. In this research, we obtained a slight loss of compressive strength when CR was used in concrete However, these rubberized concretes with a small amount of rubber provided sufficient compressive strength results (greater than 50 MPa). Due to the pozzolanic reaction, we see that compressive strength results after 56 days in glass powder modified samples increased by 11–13% than 28 days com-pressive strengths, while at the same period control samples increased its compressive strength about 2.5%. Experiments have shown that the flexural strength of rubberized concrete with small amounts of CR increased by 3.4–15.8% compared to control mix, due the fact that rubber is an elastic material and it will absorb high energy and perform positive bending toughness. The test results indicated that CR can intercept the tensile stress in concrete and make the deformation more plastic. Fracturing of such conglomerate concrete is not brittle, there is no abrupt post-peak load drop and gradually continues after the maximum load is exceeded. Such concrete requires much higher fracture energy. It was obtained that FCR particles (lower than A300) will entrap more micropores content than coarse rubbers because due to their high specific area. Freezing-thawing results have confirmed that Kf values can be conveniently used to predict freeze-thaw resistance and durability of concrete. The test has shown that modification of concrete with 10 kg fine rubber waste will lead to similar mechanical and durability properties of concrete as was obtained in control concrete with 2 kg of prefabricated air bubbles.

The surface protection can improve the waterproofness of concrete, thus reducing the saturation inside and improving the freeze‐thaw resistance (FT). Polyvinyl alcohol (PVA) membranes with different thicknesses and silane with varying impregnation depths are selected to improve the FT resistance of concrete as surface protection. The damage morphology, mass variation, ultrasonic pulse velocity, and mechanical characteristics of concrete after 125 FT times are analyzed according to the slow freezing method, and the damage mechanism is studied by scanning electron microscope in different depths of concrete. The results show that PVA membrane can improve the FT resistance of concrete and do better than silane because the silane can only keep dry inside the concrete but the surface still spalls off. And, the protection effect of PVA is a negative correlation with membrane thickness because the thicker the PVA membrane the better the air tightness and the membrane is easier damaged. On a microscopic level, the damage of PVA‐protected concrete is gradually weakened from the surface of concrete to inside, and there is an obvious boundary between the damaged and undamaged zone of silane‐protected concrete. This article provides a new idea for FT protection of concrete.
