Evaluation of the superplasticizer effect on the workability and
Superplasticizer (SP) is important for enhancing the workability and setting time of concrete in hot weather. Hence, an expe-ri-mental investigation was conducted to determine the optimum dosage...
Technical optimization and life cycle assessment of environment
The Nuclear magnetic resonance ( 1 H NMR) spectra of the superplasticizer samples were obtained at 25 °C using an ARX-400 (Bruker Co., Germany). During the test, deuterated water (D 2 O) was used as the solvent, and tetramethylsilane (TMS) was used as the internal standard.
Effectiveness Assessment of Superplasticizer Admixtures: Case of Self
for all the variants studied (according to the type of superplasticizer and the addition used). Figure 4: Flexural strength results at different cur ing ages 3.4.3 Splitting Tensile Strength
Effect of Superplasticizers to Enhance the Properties of Concrete
The experiments were classified into two phases: the first phase focused on the effects of superplasticizer admixture on workability and compressive strength, and the second phase determined the...
Effect of Superplasticizer on Workability and Properties of Self
This research examined the effect of superplasticizer on workability and properties of self-compacting concrete (SCC). Three types of superplasticizers Conplast SP 561, Conplast SP 430 and...
- Why is superplasticizer important?
- This person is not on ResearchGate, or hasn't claimed this research yet. From recent issues of stability, particle suspension, particle segregation, flow characteristics and cohesiveness in concrete, Superplasticizer has played an important role in this part.
- Does superplasticizer affect workability and properties of self-compacting concrete (SCC)?
- This research examined the effect of superplasticizer on workability and properties of self-compacting concrete (SCC). Three types of superplasticizers Conplast SP 561, Conplast SP 430 and Conplast SP 264 at different percentages (0, 10, 20 and 30%) with the same water cement ratio of 0.3, with M30 grade of concrete.
- How many types of superplasticizers are there?
- Three types of superplasticizers Conplast SP 561, Conplast SP 430 and Conplast SP 264 at different percentages (0, 10, 20 and 30%) with the same water cement ratio of 0.3, with M30 grade of concrete. The workability slump, v-funnel and l-box the test carried out on fresh concrete. Compressive strength test was carried out on the hardened concrete.
- Which type of superplasticizer is used in SCC?
- Where well particle dispersion is required superplasticizer is used which give essential proper ties of filling, passing and segregation resistance when placed. Superplasticizer fresh paste . The fresh and harden ed propertie s of SCC where studied by on the suitable
- What is polycarboxylate superplasticizer (PCE)?
- 1. Introduction Polycarboxylate superplasticizer (PCE), when applied in cement-based materials such as cement paste, mortar and concrete, can significantly improve the workability, strength and durability of the material ( Zheng et al., 2019) by dispersing agglomerated cement particles ( Zhang et al., 2020 ).
- How are superplasticizer samples characterized?
- The superplasticizer samples were characterized with a Fourier transform infrared (FTIR) (VERTEX 70, Bruker Co., Germany) instrument with a transmission mode of 400–4000 cm −1 and a resolution of 4 cm −1. The Nuclear magnetic resonance ( 1 H NMR) spectra of the superplasticizer samples were obtained at 25 °C using an ARX-400 (Bruker Co., Germany).
