Phosphate based binders are high early strength materials with a short setting time. Usually, they are used as rapid repair material for concrete structures. The feasibility of a basalt fiber reinforced inorganic binder for strengthening concrete was studied. We successfully compounded suitable phosphate binder (PB) for concrete strengthening. In the current paper, phosphate binder was to adjusted to has excellent workability, suitable setting time and fluidity. Compressive strength of phosphate binder mortar, bonding strength between PB and Portland cement mortar, and strengthening effect of PB sticked basalt fiber on concrete beam were measured. Results showed that PB has excellent adhesion with Portland cement mortar. The strengthening effect of basalt fiber reinforced PB composite on concrete beam is evident. It is feasible that concrete strengthening by basalt fiber reinforced inorganic adhesive.

Fiber Reinforced

In order to research the influence of basalt fiber on the crack and deflection of the reinforced concrete beams, four basalt fiber reinforced concrete beams with the key parameters of length which were 12mm and 30mm and volume ratio which were 0.1% and 0.2% were designed and made. The test data was obtained through the bending experiment and the comparison with the common reinforced concrete beam. The result shows that it is obvious to control the crack and deflection of the test beams with the increasing of basalt fiber characteristic parameters. The calculation method of the maximum crack width of the basalt fiber reinforced concrete beams were presented based on the method of common concrete beam, which can provide the theoretical basis for the engineering practice.

Fiber Reinforced

In order to research the influence of the shear capacity of reinforced concrete beam with the incorporation of basalt fiber, four basalt fiber reinforced concrete beams with parameters of length and volume ratio were designed and made. The fiber lengths were 12mm and 30mm, and the volume ratios were 1‰ and 2‰. The test data of basalt fiber reinforced concrete was obtained through the shear experiments and comparison with the common reinforced concrete beam. The results of the experiment show that the cracking load of the basalt fiber reinforced concrete beam increase obviously with the growing of fiber characteristic parameters, and effectively reduce the diagonal crack width.

Reinforced Cement

Basalt fiber is highly active when react with cement, thus was used as a replacement of steel rebar to enhance the flexural performance of cement mortar. Basalt fiber and its grid fabric were used in this study. The resulting bending strength revealed that the bending strength of short fiber and grid fabric reinforced mortar were improved 29.4% and 49.03%, respectively. The bending strength of mortar reinforced by the combination of short fiber and grid fabric increased up to 59.57%, which is significant.

The Impact

The strengthening effect of basalt fiber-reinforced epoxy coatings was investigated with regard to their areal weight and position on the compression or tension side of plywood. Beach plywood was coated on one side with a basalt fiber-reinforced epoxy matrix. Two biaxial and one twilled fabric with areal weights of 170 g/m2, 210 g/m2, and 340 g/m2 respectively were used. The thickness of the plywood was 21 mm. The results showed the best reinforcing effect was obtained with the highest weight when mounted on the tension side of the parallel specimens. The bending strength of these specimens was improved by 15.7%. The perpendicular specimens were positively reinforced by the fiber-reinforced polymers on both the compression and tension sides. The tension reinforcement provided a higher deflection, which was further analyzed using digital image correlation. The evaluated data indicated significant displacement of the neutral axis. The impact strength of the parallel specimens was not improved by the reinforcement, but all of the reinforced perpendicular specimens were significantly strengthened.

Positive Effect

The effect of retarding admixture on the fresh and hardened behaviour of different types of cement mortars and pastes when using a retarding admixture was investigated in this study. The types of cement used are; White cement (WhC), Ordinary Portland cement (OPC) and Sulphate Resistant Portland cement (SRC). Different cement mortar and paste mixes were cast, for this purpose, with and without the admixture. Initial and final setting times, compressive strength, length change, absorption and density for these mixes were examined at the curing ages of 3,7,28,45 days. The results showed that the addition of retarding admixture delayed the setting time significantly of WhC paste. The retarding admixture has a positive effect on the compressive strength of the mortar specimens for all types of cement used. regarding the length change test, the admixture was found to reduce the initial expansion for all types of cement at all ages. The results also showed an increase in the density and decrease in water absorption, especially at the later ages for all types of cement.  Among all cement types used, WhC was noticeably the most affected type by using the retarding admixture compared to other types of cement used.
