internal curing is promoted as a way tpo mitigate autogenous shrinkage in high-performance concrete having a low water binder ratio (w/b). Different methods of internal curing have been proposed. In this study, the effect of substituting 20% of normalweight sand by an equal mass of lightweight sand on the development...

Self-Consolidating Concrete (SCC) mixtures for use in Prestressed Concrete applications are evaluated in this paper . Twenty one SCC mixtures were made under laboratory conditions with varying water to cementitious materials ratios, sand to total aggregate rations, and cementitious materials combinations (type III cement , class C fly ash,...

Banyak penelitian yang telah menggunaka serat baja dalam campuran beton normal dan telah dilakukan dalam beberapa negara bagian di dunia. Namun, dikarenakan harga serat kawat baja itu sangat mahal di Indonesia, maka penggunaan serat kawat bendrat untuk menggantikan serat baja itu dan menggunakannya dalam campuran beton yang diteliti dalam penelitian...

The columns of a building must be stronger than the beams. The aim of this study is to obtain the cause of the long-term deformation difference by shrinkage between the beams and columns of high performance concrete with compressive strength of 60 MPa. This research was done experimentally in Indonesia...

The directional solidification which is not toward to riser causes the shrinkage defect. This defect can
be predicted by investigating the temperature distribution in riser or casting products. The goal of this
research is to examine the temperature distribution using Finite Element Software (ANSYS) and then an
ad hoc experiment has been performed...

In high-rise building, inelastic deformation due to concrete creep and shrinkage can cause internal forces redistribution. This study investigates the influence of the differential of loading method, age at loading, and column reinforcement ratio to the internal forces, differential shortening of vertical structural component, and beam-column bending moment redistribution. The...
