how to select the topics in concrete technology as a mini project?
Choose a topic that is suitable to you (probably one in which you have an interest). Have clear project objectives. Generally the outcome of the project must be such that it is useful to the employer as well as the candidate.

SELF-DESICCATION AND ITS IMPORTANCE IN CONCRETE TECHNOLOGY
Self desiccation occurs in all types of concrete due to the chemical shrinkage that takes place when water is attached to the cement. In High Performance Concrete the low porosity makes the effect of self-desiccation much more pronounced.
This paper presents a summary of a Nordic Seminar on Self-Desiccation in Concrete held in Lund. For this purpose aspects of mix design, curing conditions, desiccation, micro-cracking, self stresses, shrinkage and frost resistance related to self-desiccation are detailed.
Keywords: Autogenous shrinkage, Chemical Shrinkage, Frostresistance, High Performance Concrete, Hydration, Internalrelative humidity, Moisture, Self-desiccation, Selfstresses
Research Projects on Concrete Technology
Strength Development of High PFA Content Concrete
The main objective of the investigation is to compare the strength development of OPC concrete and PFA concrete, subject to various curing environments and durations, and derive correlations between the 28-day strength and the long term strengths.
Investigation of Cracks at Shek Wu Hui Treatment Plant
The main objective is to investigate the cause of extensive cracking of the concrete at the Shek Wu Hui Treatment Plant at the request of the Standing Committee on Concrete Technology (SCCT). The extensive cracking present in the concrete walls of the sedimentation and aeration tanks is likely to be due to alkali silica reaction (ASR).
Laboratory Investigation into the AAR Potential of Volcanic Rocks from Anderson Road Quarries
The main objective of the investigation is to provide information for the evaluation of the suitability of the use of such rocks as aggregates in concrete. The investigation is to find out the alkali aggregate reaction potential of the volcanic rocks from Anderson Road Quarries.
Recycling of Demolished Concrete as Aggregates
It is to investigate the suitability of the use of recycled aggregates in structural concrete. No unified specification has been established. The promotion of using recycled aggregates with respect to the quality control on production of recycled aggregates still needs further considerations.
Corrosion Rate of Steel Bars Produced by "Tempcore" Process
The main objective of the investigation is to compare the surface rusting of the two types of steel reinforcement bars under various exposure conditions. It is to investigate the development of surface rusting of steel reinforcement bars produced by conventional hot-rolled method and by the Tempcore process.
Comparative Study of Compressive Strength of 100mm Vs 150mm Concrete Cubes
The main objective of the study is to investigate the suitability of specifying 100mm cubes in construction works and to propose suitable compliance criteria for assessing the quality of concrete using the 100mm cubes.
Study on Use of Recycled Aggregates in Structural Concrete
The objectives are to collect data/information to support the proposed amendments to the General Specifications for Civil Engineering Works (Hong Kong Government, 1992) in promoting the use of recycled aggregates in Civil and Structural Engineering Works.
Testing of Aggregates for AAR Potential
The investigation aims to introduce to readers briefly the types and mechanisms of the AAR. It also covers the use of different accelerated mortar bar test (AMBT) methods by the Public Works Central Laboratory (PWCL) of the Geotechnical Engineering Office (GEO), Civil Engineering Department (CED), for assessing the AAR potential of aggregate in Hong Kong and the conclusions and recommendations drawn.
Durability Study for Normal Grade Concrete with Recycle Aggregates
The purpose of this project is to compare the properties of different mixes of concrete produced with natural aggregate and produced using recycled aggregate, with 20% and 100% replacement by weight, and with 0% and 35% PFA replacement. Concrete cubes, concrete cylinders and concrete prisms are cast for testing.
