Abstract

A project is proposed to develop cost effective, high porosity, moderate strength cement based materials that can be used in high performance magazine construction for both structural and shock absorbing purposes. The material will need to have a compressive strength of 2500 psi, pore content of less than 60%, have ingre- dient costs less than $200/yd, and be easily processed. The re- quired strength and high pore content are the most difficult to reconcile but this should be achievable if the pore size is kept to a minimum. Costs will be kept to a minimum by only using raw in- gredients that are within the cost constraints imposed. Process- ing, while not optimized in this proposal, will only use equipment commonly available in the construction industry. The focus of the project will be to have a material that can be placed in the fields but methods that are more appropriate for pre-fabricated sections will also be considered. The materials produced will be tested for their structural suitability with the assistance of Construction Technology Laboratory who will conduct creep and shrinkage studies, examine the development of the bond between reinforcing steel and the porous structural material then designing and testing of some simple structural elements.
