Performance Based Analysis and Design of Concrete Mix Proportions

Simulation models for predicting materials, mix proportion, time and environment dependent properties of concrete are studied. At present, the studied properties are workability, workability loss, bleeding, plastic shrinkage, strength, thermal cracking, autogenous and drying shrinkages, cracking resistance, carbonation, chloride induced corrosion, and sulfate resistance. Computer software is being developed for analysis and design purposes to obtain mix proportions of concrete with the required initial and long-term performances. Results of the research works are utilized in the establishment of “Design Considering Durability and Service Life” for concrete structures in Thailand.

Proper Use of Binders and Fillers as Cement Replacing Materials in Concrete

Studies on the properties of concrete with various kinds of powder materials are conducted. The materials are: fly ash and CaCO₃ powder, etc. Optimizing the use of these materials and introduction of multibinder systems to the concrete industry are the aims of this project. Effect of fly ash with high free lime and SO₃ content on properties of concrete is also studied for modifying the current fly ash specification.

Use of Bottom Ash in Concrete

The use of bottom ash as partial replacement of fine aggregate is studied. Some merits were observed when the replacement proportions and other control properties were appropriate. The targets of this study are to introduce the use of bottom ash to the concrete industry as well as to establish a standard for utilizing bottom ash as a partial replacing material for fine aggregate.

Maintenance of Concrete Structures

Research works and their applications on inspection, repair, maintenance, life cycle evaluation, and maintenance management of concrete structures are carried out. The works are parts of the program to develop appropriate maintenance codes and standards for concrete structures in Thailand.
