INVESTIGATING SHRINKAGE CHANGES OF NATURAL POZZOLAN BASED GEOPOLYMER CEMENTPASTE
Shrinkage behavior of a geopolymer cement paste prepared from pumice-type natural pozzolan was studiedby changing parameters of chemical composition including SiO2/Na2O molar ratio of activator and total molar ratiosof Na2O/Al2O3, and H2O/Al2O3. For investigating the effect of curing conditions on shrinkage, hydrothermal curingwas also applied. The obtained results clearly revealed the governin...
متن کاملMathematically Natural Concrete Incompleteness
Every order invariant R ⊆ Q has a maximal nonnegative root, where S1...n|>n = S0...n-1|>n. Every order invariant R ⊆ Q has a # basis containing its upper shift. These are proved here by going well beyond the usual ZFC axioms for mathematics, using the consistency of the system SRP (Con(SRP)). Here SRP is the extension of ZFC by certain well studied large cardinal hypotheses (existence of cardin...
متن کاملStructural Health Monitoring Paradigm for Concrete Structures
Structural health monitoring has been one of particular concerns of the engineering community. Effective monitoring, reliable data analysis, rational data interpretation and correct decision making are challenging problems for engineers who specialized in structural health assessment field. Concrete structures were constructed for various purposes in a certain design life in the context of 'mai...
