Bond strength of polymer lightweight aggregate concrete

Abstract

Bond strength, physical, and mechanical properties of lightweight PC were investigated with inclusion of pumice lightweight aggregate in maximum size of 12 mm. As binder material, epoxy resin‐based polymer was used with its hardener. The binder to aggregate ratio was 30% by weight. In addition, steel fibers were added to lightweight PC mixtures in ratio of 0, 0.5, and 1%. After lightweight PC mixture was prepared, it was poured in the molds with different type of steel‐bars in size of 100 × 100 × 100 mm3. The steel‐bars centered in the cubic molds, and they were in size of Ø12, Ø14, and Ø16. The specimens were cured at 60°C for 2 h. On the hardened polymer lightweight concrete (PLC), pull‐out test for bond strength and compressive strength tests were performed. Moreover, ultrasonic pulse velocity, water absorption by weight, specific porosity, and density experiments were carried out. The relation between physical and mechanical properties showed that PLCs become more durable when using ratio of steel fibers. POLYM.

Characteristics of fired clay bricks with pumice additive

“…Uygunoglu et al [32] reported that lightweight polymer concrete with pumice aggregate has a unit weight of 1346 kg/m 3 . Although these values are great, lightweight polymer concrete has a few disadvantages such as its cost which is very high and very low heat and fire resistance.…”

“…Pumice has been widely used to produce lightweight concrete [26,[31][32][33]. However, very limited information on the usage of pumice as pore maker in fired clay brick production has been reported.…”

Analysis of shrinkage and creep behaviors in polymer-coated lightweight concretes

“…The half-open porous structure of pumice aggregates mostly causes the increase of compressive strength by improving the adherence between the binder and the aggregate. However, because of the half-open surface structure of pumice, the polymer concrete (PC) needs more binding material than a PC with a normal aggregate [2] . Some researches have stated that the different mechanical features found in polyester-based PCs are related to the type of thermosetting resin or mineral aggregates, and to their concentrations in composite [3] .…”
