While seawater sea sand concrete (SSC) is similar to freshwater river sand concrete (FRC) due to its mechanical properties [3], [4], [5], reasonable development and utilization of seawater and sea sand can significantly alleviate …
How to Sand a Concrete Floor to get the surface good-looking? Sanding a concrete floor can be long and arduous, but it's well worth the effort when you're finally finished. Sanding your concrete floor will give it the smooth and silky look you have always wanted, making the surface much easier to clean in the future.
The evolution law of the pore structure of concrete is important for the study of concrete durability. To study the quantitative relationship between pore structure and macroscopic mechanics of aeolian sand concrete (ASC) under carbonation-dry-wet cycle (DWCs), the fractal characteristics of ASC under carbonation DWCs were analyzed by …
Miller has numerous sand & gravel pits that produce a variety of sands, stone, peastone, and chip. The sand & gravel pit based products can be used for granulars / road based but are also commonly screened/ washed to produce septic / filter sands, peastone, blend sands and asphalt & concrete aggregates.

In this paper, the types, formation time, structural morphology, and influence of steel corrosion products in seawater and sea-sand concrete were studied, and the intermediate and final …
Mersing Concrete Sdn Bhd was incorporated on 26 November 1996 with the setting up of the Mersing plant operating with 8 mixes trucks in the year of 1996. We then expanded our business by establishing more plants to the state of Johor, Pahang and Negeri Sembilan.
This study provides a pathway to alleviate the corrosion risk of steel reinforcement when used in chloride-contamined concrete, exploring the practise use of seawater sea sand concrete with traditional carbon steel bar.
From water resistance, UV protection, and crack-filling, our guide covers the best concrete sealers for driveways, garages, patios, and more.
The properties of sand, specifically the gradation and fineness modulus of sand, are among the principal factors known to affect the performance of both fresh and hardened concrete [8, 9 ...
Semantic Scholar extracted view of "Optimization of the mix proportion for desert sand concrete based on a statistical model" by Wenlong Yan et al.
Dune sand (DS) concrete (DSC) has attracted increasing attention due to the scarce of river sand and the abundance and low cost of DS. To promote more…
The bond strength between fiber-reinforced polymer (FRP) bars and seawater sea sand concrete (SWSSC) is a critical factor in structural design and app…
Construction of offshore engineering is faced with the challenges of easy corrosion of reinforced concrete and the scarcity of river sand and fresh water. Therefore, the use of seawater and sea sand in concrete construction has raised concerns worldwide in recent years [ 1 ]. However, a large number of chloride ions inside the seawater and …
