This paper presents experimental results on the influence of printing directions on the strength of 3D printed concrete (3DPC) using materials available in Vietnam. The experimental results show that the printing direction has a significant influence on the strength of 3DPC with and without fiber, in which the X-direction printing samples has the lowest strength, only about 30-40% of the compressive strength and 20-30% of the flexural strength of the casted samples.

The distance from the nearest concrete exposed surface to the centroidal axis of main longitudinal steel reinforcing bars, so-called axis distance, plays a critical role in ensuring the safety of reinforced concrete (RC) structures under fire, as it helps the rebars not being directly exposed to heating in a fire incident.

The extensive range of fillers used nowadays indicated the major significance of filler in the plastic industry. Although their original purpose was to lower the cost of the molding compounds; prime importance is now attached to selective modification of the properties of a specific plastic.

The purpose of this research is to analyse the available design equations and present the applicability of these equations for their use in the design of beams made of higher concrete strengths. In the present program concrete having compressive strength of 50MPa or more is considered as high strength concrete. Analytical investigation on HSC beams is made under four different aspects namely flexure, ductility, deflection and shear.

This research investigates the physical and mechanical properties of mortar incorporating fly ash (FA), which is by-product of Duyen Hai thermal power plant. Six mixtures of mortar are produced with FA at level of 0%, 10%, 20%, 30%, 40%, and 50% (by volume) as cement replacement and at water-to-binder (W/B) of 0.5.

This paper presents a computing module for a quick determination of flexural strength of fibre-reinforced concrete, plain concrete and hybrid cement composite. The hybrid cement composite consists of two layers of plain concrete and steel fibre-reinforced concrete. Both of these concretes are self-compacting ones.

In this study, the effect of polyvinyl alcohol (PVA) content, i.e. from 2 to 6% by vol. of concrete, on the flexural behavior of ECC with a desired compressive strength of over 60 MPa, in which fly ash and silica fume were selected as supplementary cementitious materials. The experimental results show that the addition of PVA fiber gives little influence on compressive strength but can significantly affect the flexural behavior of ECC.

This paper presents an experimental study on the effect of prestressing force on the flexural behavior of unbonded prestressed concrete (UPC) strengthened by Carbon fiber reinforced polymer (CFRP) sheets. The testing program was carried out on nine large-scale UPC rectangular beams. The investigated parameters included the reduction of prestressing force (0%, 15%, and 30%) and the number of CFRP layers (0, 2, and 4 layers).

This study aims to use FA and GGBFS to replace 50% cement in the production of LFC. Various PP fiber contents were also incorporated to enhance the mechanical strength of LFC. Then, the influence of PP fiber content on the engineering properties of LFC was investigated in terms of fresh unit weight (UW), dry density, water absorption, thermal conductivity, flexural strength, compressive strength, and ultrasonic pulse velocity (UPV).

Samples were molded under a hot press and for each sample 50 test samples obtained by cutting them with a water jet. The obtained samples were characterized by TG, FTIR, and SEM. The effect of water absorption was evaluated by measuring percentage water absorption and flexural strength of samples over 9 months. The results revealed that filler addition lowers the damage created by distilled water a considerable amount and addition of hydrophobic fillers to epoxy matrix composites can be especially beneficial for applications where long-term water exposure is desired.
