This work aims to investigate the damage in ultrahigh‐performance concrete (UHPC) caused by freezing‐thawing action. Freezing‐thawing tests were carried out on UHPCs with and without steel fibers. Mercury intrusion porosimetry (MIP), scanning electron microscopy (SEM), X‐ray computed tomography (X‐ray CT) applied detect microstructure of UHPC matrix before after tests. The results showed that possessed very excellent resistance due its dense microstructure. After action, cracks occurred...
Fly ash (FA) has been widely used in cement-based materials, but limited work conducted to establish the relationship between compressive strength and hydration process of high-volume FA (HVFA)-cement-based material. In this study, chemically bound water contents FA-cement-based materials with different water-to-binder ratios (0.4, 0.5, 0.6) (0%, 30%, 40%, 50%, 60%, 70%) were tested. Replacing more cement reduced HVFA-cement-based materials. The content by about 60-70% when 70% was replaced...
The cracks in concrete are a fast transport path for chlorides and influence the service life of structures chloride environments. This study aimed to reveal effect crack geometry on diffusion cracked concrete. process was simulated with finite difference method by solving Fick’s law. results showed that apparent diffusivity lower more tortuous cracks, narrow points also diffusivity. For higher width meant relatively straight consequently, diffusivity, while resulted depth significant...
In this study, the durability of nano-TiO 2 modified ultra-high performance concrete (UHPC) with and without a flexural load was experimentally investigated.Firstly, mechanical properties UHPC various contents were tested, results showed that 1 wt.% exhibited best properties.Then, added into to evaluate its effects on dry shrinkage, chloride ingress resistance, freeze-thaw resistance carbonation UHPC.The effect also studied.The shrinkage reduced compared control accelerated penetration...
The chloride diffusion coefficient is the most important parameter when predicting ingress in concrete. This paper proposed a model for calculating of steel fiber reinforced concrete (SFRC). Considering structures service are usually subjected to external loads, effect bending load was discussed and expressed with stress factor k s model. cement paste calculated capillary porosity then used predict SFRC. Some factors were determined experimental results. Chloride bulk tests performed on SFRC...
The early age volume deformation is the main course for cracking of high-performance concrete (HPC). Hence, shrinkage behavior and restrained stress development HPC under different restraints curing conditions were experimentally studied in this paper. method to separate components total restraint was proposed. separated into autogenous stress, drying thermal stress. results showed that developments free (autogenous shrinkage) accelerated when began; but began did not significantly influence...
