The effect of a plasticizing admixture on the properties of hardened concrete

Mokslas – Lietuvos ateitis / Science – Future of Lithuania
Concrete is material obtained mixing matrix material, coarse and small aggregates and water along with additives acquiring necessary properties of hardening. The quality and properties of raw material used for manufacturing concrete, V/C ratio and the uniformity of the compaction of the mixture lead to the fundamental properties of concrete.

A Parametric Computational Framework for Modeling and Seismic Design of Post‐Tensioned Mass Timber Rocking Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Post‐tensioned cross‐laminated timber (PT‐CLT) rocking walls offer a compelling seismic system combining self‐centering behavior with energy dissipation. However, progress in their performance assessment and design has been limited by the lack of a comprehensive parametric modeling tool, as exists for steel or reinforced concrete systems. This

Numerical Simulations of 5‐Story Building Using Wood Light‐Frame Shear Walls and Post‐Tensioned Cross‐Laminated Timber Rocking Wall Dual Systems

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study explores the seismic performance of a five‐story prototype building using different configurations of a dual lateral force‐resisting system (LFRS) combining post‐tensioned cross‐laminated timber rocking walls (PT‐CLT‐RW) with conventional wood light‐frame shear walls (LiFS).

STRUCTURAL AND THERMOPHYSICAL PROPERTIES OF HARDENING CONCRETE

Наука и техника, 2012
Structural and thermophysical properties of thermally treated concrete have been studied in the paper. The paper demonstrates regularities of changes in structural and thermophysical properties of concrete during heat treatment process. It is established that stabilization of coefficient values for heat- and temperature conductivity of concrete ...

Performing history, negotiating patriarchy: Actressing as gendered labor and the fragmentation of womanhood in Chinese historical costume drama

Feminist Anthropology, EarlyView.
Abstract Gender inequality remains widespread in the film and television production industry, yet it is seldom examined in relation to backstage working environments. This article integrates on‐screen and off‐screen perspectives to investigate the working lives of Chinese actresses.
