Mechanical and dynamic properties of high strength concrete modified with lightweight aggregates presaturated polymer emulsion

Damping Property of Cement Mortar Incorporating Damping Aggregate

“…Nowadays, the characteristics of ultra-high rise, high-speed, and large-flow traffic in building construction and transport engineering became more prominent [4,5]. Therefore, cement-based materials and their structure inevitable exposure to dynamic loads during service [6][7][8]. The vibration energy induced by external dynamic loads cannot be dissipated effectively by cement-based materials itself on time.…”

“…The damping property is the ability to translate the vibration energy of a system into other forms of energy [6,7,10], which effectively reduce the vibration of structure [6]. In view of the low damping capacity of cement-based materials [7], many studies reported that adding polymer emulsion [11] into cement-based materials is an effective way to improve its damping property due to the polymer emulsion has high flowability, excellent viscoelastic and damping performance, etc.…”

“…In view of the low damping capacity of cement-based materials [7], many studies reported that adding polymer emulsion [11] into cement-based materials is an effective way to improve its damping property due to the polymer emulsion has high flowability, excellent viscoelastic and damping performance, etc. [6,[12][13][14][15]. For example, Tian et al [6] prepared the lightweight aggregate presaturated polymer emulsion (LAP) and water (LAW) and investigated the replacement percentage of LAP on the damping ratio of concrete; the results indicated that the damping ratio of concrete increased with the increased of LAP%, and the increasing tendency produced by LAP% was much more obvious than that the LAW%, at the same volume fraction.…”

Numerical Simulation of Tensile Failure of Concrete in Direct, Flexural, Double Punch Tensile and Ring Tests

“…The use of concrete structural elements can be easily found in buildings, highways/bridges, runways, jetties, etc. Many experimental and theoretical studies have been carried out to determine the tensile strength of concrete [1][2][3][4][5][6][7][8][9][10][11][12]. Direct tensile test is first method for determination of tensile strength.…”

A New Approach for Measurement of Tensile Strength of Concrete

“…Therefore, many experimental and theoretical studies have been carried out to determine the tensile strength of concrete [1][2][3][4][5][6][7][8][9][10]. It is known that the stress obtained by breaking a specimen which is subjected to uniaxial loading, shows the real tensile strength of concrete ( Fig.…”
