“…In the study in question, a new generation polycarboxylate supported super plasticizer was used to ensure workability and prevent segregation due to low water-to-cement ratios (w/c). It is known that chemical additive content increases concrete strength (Tugrul Tunc, 2019). The physical/chemical properties of the waste marble powder and silica fume used in this study and the characteristic properties of the chemical additive are presented in Table 2.…”

High performance lightweight concrete (HPLC) is a new and original research in structural engineering. Due to the high risk of earthquakes, which is one of the biggest disasters today, the need for HPLCs has increased. The purpose of this study is to experimentally research concrete-reinforcement bond for the change parameters such as different reinforcement diameters and different embedded lengths. For this purpose, HPLCs with different mix ratios and different concrete components were prepared by using pumice aggregates. Within this scope, HPLC beam specimens of 100×180×800 mm dimensions were prepared and produced specimens were subjected to the Standard Belgium Hinged Beam (SBHB) test. There are limited studies in the literature on the investigation of the bond properties of HPLC beams with this test. The mentioned study draws attention with this aspect. In the present study, ribbed steel reinforcement bars with different diameters were used. The beam specimens were produced considering the different embedded lengths for each reinforcement diameter. The bond tests were performed. Using the load applied vertically and read with the help of the load cell in the experiment, the bond stress occurring in the reinforcement was calculated with the help of the force in the reinforcement indirectly found. As a result of the experiments, it has been determined that there is a significant relationship between bond stress and reinforcement diameter and embedded length. It has been determined that the bond stress decreases with the increase of reinforcement diameter and embedded length.

Concrete is a valuable construction material with high mechanical strength and durability, used extensively in the construction industry. It is produced by mixing sand, stones, cement, and water in different proportions depending on the desired quality of the final product. Water reducers are additional chemical ingredients used in concrete to reduce the quantity of water required in the concrete mixture. When added to concrete, water reducers increase the workability and flowability of concrete in the freshly mixed state and improve the mechanical strength and durability of the final hardened product. This review paper describes the different types and applications of concrete water reducers used in the construction industry including their working mechanisms and fluidity effects on concrete properties. It discusses the production of synthetic and bio‐based concrete water reducers and reviews the present challenges involved in the preparation of bio‐based concrete water reducers from renewable resources. © 2023 Society of Industrial Chemistry and John Wiley & Sons Ltd.

In reinforced concrete structures, one of the most important factors for structural safety is the quality of concrete. The first thing that comes to mind for concrete quality is the compressive strength of concrete. However, properties such as elasticity modulus are also among the properties that determine concrete quality. Since concrete is a brittle material, different methods are used to determine dynamic elasticity modulus. In practice, dynamic elasticity modulus of concrete can be identified by utilizing concrete compressive strength value. In this context; compressive strength tests were performed on a series of concretes accordingly relevant standards. Since it is difficult to determine elasticity modulus from the stress and strain relationship, the dynamic elasticity modulus values in this study was calculated using empirical formulas according to TS 500-2000, ACI 318-95 and CEB-FIP 1978 on the basis of experimental data in this study. The relationship between the calculated dynamic elasticity modulus values and concrete compressive strength was analyzed. From the study, it is concluded that as concrete compressive strength increases, dynamic elasticity modulus increases for the concrete specimens.
