Development of Reactive MgO Cement-Silica Fume–Based Strain-Hardening Engineered Cementitious Composite
(ASCE, 7/26/2023 )MgO-based cementitious materials have attracted increasing attentions due to their advantages of low energy consumption, fire resistance, and low CO2 emission. This study develops a new reactive MgO cement (RMC)-silica ... -
Sustainable Lignin to Enhance Engineering Properties of Unsaturated Expansive Subgrade Soils
(ASCE, 5/31/2023 )New ways to apply sustainable materials, such as biomass components, are essential for reducing dependence on fossil fuels. This work investigated the engineering properties of unsaturated expansive subgrade soils stabilized ... -
Shock Wave–Induced Dynamic Mechanical Behavior of Calcium Silicate Aluminate Hydrate at the Molecular Scale
(ASCE, 5/25/2023 )Calcium silicate aluminate hydrate (C-A-S-H) is the main hydration product of cement mixed with industrial wastes. The purpose of this study is to understand the dynamic mechanical behavior and structural transformations ... -
Comparing Strength and Modulus of Elasticity Values for Prisms Constructed with Lightweight and Normal Weight Grout
(ASCE, 5/16/2023 )Current masonry design standards allow for the use of lightweight concrete masonry unit (CMUs), but lightweight grout is not an approved building material. An experimental test program was conducted to compare the compressive ... -
Influence of Interparticle Separation Distance on the Fresh and Hardened Behavior of Ecoefficient Cement Pastes
(ASCE, 5/30/2023 )An efficient method to produce ecoefficient cementitious mixtures is using particle packing models (PPMs) combined with limestone fillers (LF). Yet, key outcomes obtained in the fresh and hardened states, including slump ... -
