“…e sample with 4% steel fibers has the highest compressive strength after 30 freeze-thaw cycles, but this decreases gradually as the number of freeze-thaw cycles increases, and the degradation becomes more obvious when the number of freeze-thaw cycles reaches 150. At higher steel fiber content, there is a reduction in compressive strength which may be due to the balling of steel fibers as reported by other researchers [13][14][15].

Low-impact development measures are a kind of ecological technology system that can easily realize urban rainwater collection and utilization to alleviate the contradiction between flooding/water logging disasters and water shortages. But most of the low-impact development measures are difficult to solve the problem of deep soil infiltration and fully utilize runoff regulation and seepage benefits. Therefore, this paper proposes the concrete microseepage well with the optimum proportion of crushed stone, cement, and water of 1 : 0.13 : 0.11 and 2% steel fiber content. The artificial rainfall experiment is applied to verify the high-infiltration of concrete microseepage well in deep soil. The numerical analysis shows that the concrete microseepage well around a single building and two adjacent buildings can all decrease 15%–40% of the pore water pressure, decrease 11%–33% of total head, and improve 43–55 times of infiltration velocity. The concrete microseepage well with 0.1 m in diameter and 1 m in height can affect the infiltration area of 1 m2. Each building being surrounded by seepage wells is the optimal layout scheme to alleviate the flooding/water logging disasters. This study provides a scientific reference for the development of sponge cities with low-impact development measures to reduce the problem of flooding/water logging disasters and water shortages.

“…For early age shrinkages fractures and concrete brittleness, hybridization of different type of fibres is an alternative approach [1]. Hybrid fibre reinforced concrete is a form of concrete that effectively combines the benefits of several fibre types to enhance its characteristics [2]. HFRC is investigated these days for its structural advantages over ordinary concrete.…”

Concrete is a popular building material because of its great compressive strength, durability, and availability of sub-components. The strain at fracture and tensile strength of normal concrete are extremely poor. Simple concrete usually contains multiple micro-cracks and fails due to a lack of tensile strength under continuous loading conditions. Concrete is strengthened with fibres to increase tensile and flexure strength. Fibre-reinforced concrete’s primary function is to monitor cracking and thus provide some post-cracking ductility. The aim is to compare the performance of fibres on the mechanical properties of M30 grade concrete and to find the optimal fibre concentration. Fibres are added by 0.5%, 1%, 1.5% and 2% in concrete. Ternary blended concrete was considered in the study. Cement is partially replaced by GGBS with 30% and Dolomite powder 10% respectively. The study took in to account the replacement to reduce the CO2 emission while also conserving natural resources. Total 8 mixes are prepared with fibre proportions. Different concrete specimens such as cubes, cylinders and beams are prepared with different proportions of fibres. Prepared concrete specimens were tested at 3, 7& 28days. The inclusion of fibres resulted in significant improvements in compression, flexure, and split tensile strength in experimental test results.

“…Thus, it is required to study the behavior of beams. Prathipati et al [2] studied uniaxial compressive behaviour of Hybrid fibre reinforced concrete (HFRC) with two different fibre lengths (glass fibre of 6mm and 12mm length glass fibre and crimped steel fibre of 25mm and 50mm length). It was found that the uniaxial compressive response of the concrete was improved by the addition of glass fibre or steel fibre to the concrete.…”

The paper presents an experimental study on the flexural performance of Conventional beam (CB), Ternary beam (TB) and fibrous ternary beam (TBF). Ternary beams are made by using 10% of Micro silica (MS) and 30% of Ground granulated blast furnace slag (GGBS) and Fibrous ternary beams were cast by incorporating crimped steel fibre in four volume fractions i.e. 0.5%, 1%, 1.5% and 2% to the predestined optimum ternary mix, was obtained from preliminary studies. The influence of Supplementary cementing materials (SCMs) and steel fibre on ultimate load, energy absorption, ductility, moment and energy factors was assessed. The results reveal that energy absorption and ductility improved by ternary beams and further enhanced by adding up of steel fibre over conventional beams.
