Abstract
This paper deals with the influence of periodic freezing on light-weight concrete characteristics. Three different sets of light-weight concrete specimens were periodically freezing and non-destructively tested over time. Another three comparative sets of light-weight concrete specimens were tested at the same time and these sets were placed in water. The main aim was to determine and compare the dynamic elastic modulus values during and after 200 freeze-thaw cycles. The methods for this non-destructive testing were the ultrasonic impulse method and the resonance method.
Highlights
The freeze-thaw resistance of concrete is related to its air void system and to the bond between the aggregates and matrix
This paper deals with a part of the results of the experimental analysis focused on the freeze-thaw resistance of the light-weight concrete
The following three figures show the mean values of the relative dynamic elastic modulus of the three types of the light-weight concrete
Summary
The freeze-thaw resistance of concrete is related to its air void system and to the bond between the aggregates and matrix. Light-weight aggregate concretes are characterized by specific distribution and the content of air voids in the matrix as well as in the aggregate particles. The main disadvantage of these concretes is their high sensitivity to the curing conditions which can significantly influence the initiation and propagation of cracks. This fact leads to the changes of physical-mechanical, fracture, and durability parameters. This paper deals with a part of the results of the experimental analysis focused on the freeze-thaw resistance of the light-weight concrete. Polypropylene fibres Forta Econo Net with a length of 38 mm and 19 mm were used as a dispersed reinforcement
