Minimizing of cement paste volume not only decreases the cost of construction but also improves many of attributions regarding durability in self-consolidating concrete. In this paper, a mixture design method of Self-Consolidating Concrete based on minimum cement paste volume is proposed that descends ...
It was also easier to produce RUN-5 to RUN-8 because the mixture was thinner, concrete hardened flat but with foam pores, and the mix was warm during the pouring process. Moreover, RUN-9 to RUN-13 were also easy to produce because the mixture was watery and the temperatures increased ...
The class-F fly ash is used as a primary binder material and cement is completely eliminated in this concrete mixture. The alkali activator is a blend of sodium hydroxide (NaOH) gel and gel of sodium silicate (Na 2 SiO 3 ) added to dry concrete materials for activating geo-polymerization ...
During the concrete mixing, a specific amount of water was introduced to improve the workability of geopolymer mixture. OPC concrete, mortar and paste specimens with grade of C40 were also prepared as a reference. The detailed mix proportions of all concrete, mortar and paste in this study are...
Recommended mixture proportion is also proposed to realize the optimum strength of expanded polystyrene concrete. The orthogonal test can help systematically investigate effects of mixture materials on the strength of expanded polystyrene concretes and optimize the design of mixture proportion....
However, there is no research that can provide a guide on the optimal mixture proportions for maintaining compressive strength and secure durability properties when using local materials. Therefore, the purpose of this article is to assess the durability and engineering performances of concrete based ...
For concrete testing, we use the ILASTIK default values of 0.300.30, 0.700.70, 1.001.00, 1.601.60, 3.503.50, 5.005.00, and 10.0010.00 [45]. In turn, regarding our semi-supervised DR approach for TF enhancement, it is worth mentioning that t-SNE-based methods require initial values ...
