The pneumatic flow mixing method was developed to stabilize dredged soil and surplus soil for promoting their beneficial use in 1999. The pneumatic flow mixing method is a new type of the ex-situ cement stabilization techniques, in which dredged soil and surplus soil is mixed with a relatively small amount of chemical binder without any mixing paddles and blades in a pipeline. When a relatively large amount of compressed air is injected into the pipeline, soil can be separated into small blocks. When binder is injected into the pipeline, the soil block and binder are thoroughly mixed by means of turbulent flow generated in the soil block during transporting. As this method has many benefits − rapid and large scale execution can be conducted with low cost − it has been applied to many land reclamation projects, backfilling behind earth retaining wall projects and shallow stabilization projects using dredged soils and surplus soils.
The book presents the state of the art in the pneumatic flow mixing method, and covers recent technologies, research activities and know-how in machinery, design, construction technology and quality control and assurance.
The Pneumatic Flow Mixing Method is a useful reference tool for engineers and researchers involved in admixture stabilization technology everywhere, regardless of local soil conditions and a variety in applications.

Loss of tension stiffening is one of three basic phenomena of concrete behaviour which leads to deflections increasing with time. It is related to the interaction of the reinforcement and the concrete. No formulae have been developed to predict how tension stiffening changes over time. In the long term, it reduces to about half its initial value. How rapidly this reduction occurs has not been studied. This makes it difficult to calculate the development of the deflections of slab structures with time. The research programme described in this report was mainly set up to solve this problem.

BS EN 1504 provides an integrated framework for the concrete repair industry and addresses all the stages of the repair process. The Standard embodies the use of products and systems which meet minimum performance requirements for a range of repair applications. The aim of the Report is to guide consultants and contractors through the application of BS EN 1504, and other related standards, so that they develop appropriate solutions and specify and apply the appropriate materials.
