2 Lightweight - Aggregate Concretes in Compression
One research field in Leipzig deals with the design of high strength lightweight-aggregate concretes (HSLWAC). Due to the huge waveband of this concretes with all possible combinations of lightweight-aggregates and mortar matrix the formulation of general rules is difficult. Therefore both components lightweight-aggregates and mortar matrix will be investigated in detail in order to achieve a d...
متن کاملEffects of Aggregate Gradation on Resilient Modulus and CBR in Unbound Granular Materials
Resilient modulus and California Bearing Ratio (CBR) in unbound granular materials are the key technical characteristics of layers in a flexible pavement design. Among the factors affecting these two parameters, the aggregate gradation is the most important. Using particle size distribution curve developed by AASHTO, together with other considerations mentioned in the related regulations have y...
متن کاملApparent modulus of elasticity of dental amalgams.
The modulus of elasticity of dental amalgam has been determined by analysis of creep data (OGLESBY ET AL, J Res Natl Bur Stan 72C: 203, 1968) and by ultrasonic methods (DICKSON and OGLESBY, J Dent Res 46: 1475, 1967; HALL ET AL, J Dent Res 52: 390, 1973) to be between 63,000 and 70,000 MN/m2. These values represent the instantaneous elastic compliance term when dental amalgam is treated as a vi...
متن کاملdeterminants of modulus of rupture and modulus of elasticity of particleboards on the basis of data base
the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...
متن کاملSelected Technological Factors Influencing the Modulus of Elasticity of Concrete
The topic of the article focuses on the evaluation of selected technological factors and their influence on resulting elasticity modulus of concrete. A series of various factors enter into the manufacturing process which, more or less, influences the elasticity modulus. This paper presents the results of concrete in which the influence of water coefficient and the size of maximum fraction of th...
