The presence of the stable and adequate air-void system in fresh and hardened concretes
are crucial to many properties, such as resistance against freeze and thaw cycle …

This paper is a bibliographic tool reviewing experimental and theoretical studies related to
cement hydration and microstructure development that have been published within the four …

Air entraining admixtures (AEAs) are surfactant-based solutions and powders that are used
to stabilize air voids in cement paste that protect concrete against frost damage. After …

Rheological properties and the interaction between air bubbles and solid particles are
important factors influencing the air bubble system in air-entrained concrete. The former may …

Cement concrete is an extensively used construction material in buildings and civil
infrastructures. As infrastructure moves into plateau areas, freeze-thaw failure is a main …

Utilization of admixtures with different action mechanisms has increased by combining them
both physically and chemically. The effect of the use of modified water reducing admixture …

This study has investigated the characteristics of air-voids structure and compressive
strength of air-entrained concrete at normal atmospheric pressure (P= 1 atm) area and low …

Air bubble instability leads to the deterioration of air-void structure and threatens the frost
resistance of air-entrained concrete, especially in plateau low atmospheric pressure …

Foam concrete with different dry densities (400, 500, 600, 700, and 800 kg/m3) was
prepared from ordinary Portland cement (PO 42.5 R) and vegetable protein foaming agent …

The influence of a new generation superplasticizer (SP) type, air-entraining admixture
