This paper expound mainly the mechanism and how control of charge cohere for DRI use coal reducing agent and shaft fumace, and illustrate the cohere can control by exampll of test and production.

Research on applications about new adhesive material of construction cracks in tunnel concrete-liner;

By means of electric anti-fiexural meter and scanning electron microscope,study and analysis were made of the influence of VAE emulsion on performances of 3 kinds of different adhesive materials.

Objective To analyze and summarize the efficiency of the united utility with the new type of adhesive material super-bond C&B and full crown restoration in treatment of the vertically fractured teeth.

In the experiments viscosity and adhesive strength variation after epoxy resin was modified with different thinners was introduced.

A study of preparation of adhesive materials for CFRP reinforced concrete structure;

The keys for successful carbon fiber reinforcing concrete structure is the adhesive property of adhesive materials.

Through bending experiment,adhesive materials failure point and load of toughened and not toughened samples are analyzed and the toughening modification of adhesive materials can improve the adhesive properties between CFRP and concrete.

It analyses the superiority of carbon cloth strengthen construction,analyses the main mechanical nature and characters of carbon cloth,researches the adapted resin binding material of carbon cloth strengthen,and specifically represents the construction technology and technique steps of carbon cloth strengthen technique to accelerate its develop.
