All jobs are different. Variables include the area the job is located, size of job, access to site, excavation, reinforced steel, concrete mix design, and the type of finish. We will price match or beat our competitors prices guranteed.
All jobs are different, but some jobs have a turn around of as little as 3 days. From start to finish. Others can take a week or more dependent on the weather, size of job, location, and concrete supply and demand.

Electro-deposition repairing concrete crack technique is of vital importance to prolong the service life of the concrete structure in the marine environment. In this paper, the repairing effect using seawater as an electrolyte was compared with ZnSO4 solutions, and the mechanism of electro-deposition repairing concrete cracks under seawater environments was investigated. Besides, various parameters such as electrode materials, electrode distances and current density were studied in seawater. The experimental results indicated that electro-deposition repair using seawater is highly effective compared to using ZnSO4 solutions. The Cl- removal efficiency can reach to 16.25% with titanium mesh as the anode and seawater as the electrolyte. The main crystal mineral composition using seawater is brucite, calcite and aragonite, and the percentages of Mg(OH)2, Ca(OH)2 and CaCO3 are approximately 68%, 7% and 23%, respectively. Rather than Na+, Mg2+ and Ca2+ in seawater were the primary ions promoting the repair of concrete cracks. When the seawater and titanium mode was used, the reaction products were the densest and the repairing effect was the best. Furthermore, when the titanium electrode distance was 0 mm and the current density was 0.25 to 0.5 A/m2, the electro-deposition repairing effect was the best. This paper presents a new method for the research of electro-deposition repairing concrete cracks in the submerged zone of marine environment.

Concrete is the most widely used building material in the world, and it plays a very important role in building modern infrastructures that stand the test of time. With the ever-increasing demand for higher performance, resilient, sustainable, and smart infrastructures, various advanced concrete technologies have been invented, researched, and implemented at a structural scale.
This special issue provides a collection of research contributions related to advanced concrete technologies and their structural use in civil engineering applications. In this special issue, 19 articles of the 30 submitted manuscripts have been selected and published, among which 6 articles are related to the studies at material scale level and 13 articles mainly focus on the concrete structural performance.
X. Peng et al. [25] studied the size effects on compressive and tensile strengths of recycled aggregate concrete. According to experimental results, both compressive and tensile strengths of recycled concrete have obvious size effects as the strength value decreases gradually with increased specimen size. They also proposed a standard neutrosophic number for modifying the size effect law on compressive and tensile strengths, which showed that the size effect law based on the neutrosophic number is more realistic than the existing size effect law.
To solve rebar corrosion in existing concrete structures, B. Yi et al. [26] conducted research on inhibiting performance of compound corrosion inhibitors based on nitrite; the results showed that the addition of phosphate can improve the macrocell corrosion caused by the low dosage or uneven distribution of nitrite, whereas nitrite has a better inhibitory effect than phosphate; additionally, brushing, perfusion, and composite repair can all play a good role in inhibiting corrosion, of which composite repair is the best.
D. S. Chen et al. [29] investigated the mechanical properties of rice husk recycled concrete (RHRC) and employed flexural test on the RHRC sandwich wall. The results showed that the compressive strength of RHRC was reduced with rising rice husk content. In term of structural performance, the RHRC composite sandwich walls have good compression resistance and no instability failure and the flexural capacity of composite sandwich walls is high enough to bear wind load.
C. H. Tang et al. [31] investigated the flexural behavior of unbounded prestressed concrete (PC) bridge girders via experimental and numerical methods; the results showed that the flexural destruction behavior in unbonded PC T bridge girders is similar to that of PC T bridge girders and the prestress degree and load location have significant influence on the destruction process in unbonded PC T bridge girders.
W. C. Li et al. [33] conducted an experimental study on bond performance between a fiber-reinforced polymer (FRP) bar and unsaturated polyester resin concrete (UPC). It was found that the failure types of FRP bar-UPC specimens depend on the interface bond stress, UPC tensile stress, and stress of the FRP bar; furthermore, the FRP bar-UPC bond strength decreases with the increase of the diameter of the FRP bar due to the shear-lag effect.
A paper by X. Peng et al. [34] proposed a robust estimate method to detect the damage of concrete structures using contaminated data. It was found that this proposed method can successfully identify the location and damage extent of a reinforced concrete beam structure even if the used data have gross errors.
A. M. Song et al. [36] investigated the static and fatigue properties of steel concrete composite beams under the hogging moment via experimental tests and analytical models and the structural deformation were also discussed. In the paper, the authors improved the presented models and gained a better agreement with test results; finally, the design recommendations of fatigue deformation were proposed. e24fc04721
