The durability of three types of wet joints in manufactured sand concrete prepared in simulated plateau environment was investigated. And the accelerated corrosion test on specimens in the chloride salt solution and the static tensile test on corroded steel bars in specimens were carried out by sequence.
Few studies have investigated the use of manufactured sand ... Additionally, the study assessed the impact of varying M-sand levels on composites' durability properties by conducting drying shrinkage, permeable voids, water absorption, and rapid chloride penetration test (RCPT) analysis.
The results indicated that a marginal increase in strength and durability properties of high performance concrete by addition of manufactured sand as a complete replacement of natural sand ...
In such a situation the manufactured sand can be an economical alternative to river sand. The manufactured sand is defined as residue, tailing or other non-valuable material after the extraction ...
Many researchers have studied the workability, mechanical properties, and durability of concrete containing manufactured sand [5, 6, 7]. The content of stone powder in manufactured sand significantly impacts the …
From the experimental results, the increase in the percentage of manufactured sand increases the compressive strength up to 60% substitution of manufactured sand for river sand, beyond which there ...
In order to explore the durability of manufactured-sand-reinforced concrete and its wet joint in a plateau environment, an integrally formed (IF) specimen and a wet joint specimen with punched ...
Keywords: - Durability, Natural Sand, Manufactured sand, Water Permeability test, Rapid Chloride Penetration test. I. INTRODUCTION Durability of concrete is defined as its ability to withstand weathering action, chemical attack or any other process of deterioration. A durable concrete requires little or no maintenance and retains its original form,
Here, industrial waste residue (fly ash and slag), sea sand (SS), and manufactured sand (MS) were used to produce UHPC under standard curing conditions to reduce the material cost and make it more environmentally friendly and sustainable. ... The Impact of RCA and Fly Ash on the Mechanical and Durability Properties of Polypropylene Fibre ...
In concrete pavement, it was found by the CCAA (2012) that the free silica limit used in the selection of natural sand to provide good skid and abrasion resistance to concrete pavement does not necessarily apply to …
The results indicated that a marginal increase in strength and durability properties of high performance concrete by addition of manufactured sand as a complete replacement of natural sand ...
For the past few years, manufactured sand (MS) has been widely used as fine aggregates in construction in China due to the overexploitation of river sand (RS). However, the stability of slurry will be unbalanced due to the irregular grain size, improper grading, and high content of powder, resulting in poor workability.
To investigate the feasibility of using manufactured sand & silica fume in place of river sand and cement under normal climatic conditions fresh, mechanical and durability properties were ...
The mechanical and some durability properties of these concretes were studied. The results showed an improvement in the workability of the manufactured sand concrete by introducing granite dust. ... Manufactured sands from limestone, granite, basalt etc. have become the green and economical substitute for river sands used in high-performance ...
The occurrence of the alkali–silica reaction (ASR) in granite manufactured sand concrete reduces its durability and service life. However, the combination and effect of different mineral admixtures on inhibiting ASR in granite-manufactured sand concrete and the in-depth understanding of the inhibition mechanism still need to be further explored. Therefore, this …
Six representative parent rocks of sand, including limestone, quartzite, gneisses, granite, Basalt and Marble were selected to conduct a systematical research on the effects of various lithologies of manufactured sand on the workability, mechanism properties, volume stability and durability of manufactured-sand concrete. The experimental results show that the …
concrete containing natural sand is having good strength and durability properties. Nowadays there is a lot of demand for the ... Manufactured Sand – M.S, Specific Gravity – G, Fineness ...
In this paper, the mass growth rate and compressive strength of manufactured sand concrete are higher than those of river sand concrete, because of the filling effect and activity …
Chemical composition of M-sand is given in Table 4.Particle size distribution curves for M-sand with different percentages of fines and coarse aggregate are shown in Fig. 1. The gradation of river sand and manufactured sand conforms to zone II of IS383:2016 [18]. Potable water was used in preparation of concrete.
The use of manufactured sand (MS) has been increasing in China because good quality natural sand is not economically available in many areas. Because of the crushing process, MS differs from natural sands in its grading, particle shape, and texture; and typically has between 10% and 20% fines (the particles passing the 75 μm sieve).
Manufactured sand is used as an alternative construction material thereby reducing the demand and dependence on naturally occurring sand. ... it is noticed that legitimately prepared M-sand enhances the strength and durability characteristics of concrete through better bonding than the river sand (Vijaya and Senthil Selvan 2015). By the year ...
The durability of three types of wet joints in manufactured sand concrete prepared in simulated plateau environment was investigated. And the accelerated corrosion test on specimens in the chloride salt solution and the static tensile test on corroded steel bars in specimens were carried out by sequence.
Manufactured sand squashed shape with grounded edges, washed and from stone or rock, otherwise called graded to as a construction material. The machine-made sand or crushed-stone sand, size of manufactured sand (M-Sand) is less has been utilized as an alternate of natural than 4.75mm. Manufactured sand is an sand in concrete.
