Influence of Alkali Activator Type on the Hydrolytic Stability and Intumescence of Inorganic Polymers Based on Waste Glass

The main objective of this study is the synthesis and characterization of low cost alkali-activated inorganic polymers based on waste glass (G-AAIPs) using a mixture of NaOH and Ca(OH)₂ as alkali activators, in order to improve their hydrolytic stability. This paper also presents detailed information about the influence of composition determined by X Ray Diffraction (XRD), microstructure determined by Scanning Electronic Microscopy (SEM) and processing parameters on the main properties of G-AAIP pastes. The main factors analyzed were the glass fineness and the composition of the alkaline activators. The influence on intumescent behavior was also studied by heat treating of specimens at 600 °C and 800 °C. The use of Ca(OH)₂ in the composition of the alkaline activator determines the increase of the hydrolytic stability (evaluated by underwater evolution index) of the G-AAIP materials compared to those obtained by NaOH activation. In this case, along with sodium silicate hydrates, calcium silicates hydrates (C-S-H), with good stability in a humid environment, were also formed in the hardened pastes. The highest intumescence and an improvement of hydrolytic stability (evaluated by underwater evolution index and mass loss) was achieved for the waste glass powder activated with a solution containing 70% NaOH and 30% Ca(OH)₂. The increase of the waste glass fineness and initial curing temperature of G-AAIPs have a positive effect on the intumescence of resulted materials but have a reduced influence on their mechanical properties and hydrolytic stability.

目的:观察四川省自贡地区高同型半胱氨酸血症(homocysteine,HCY)人群的中医体质分布、中医体质与心血管危险因素的相关性,为建立治未病同健康管理相结合的模式干预高同型半胱氨酸血症提供依据。方法:通过调查514例高同型半胱氨酸血症人群填写的《中医体质分类与判定表》的情况,搜集基本信息及实验室检查,探讨中医体质分布和危险因素的相关性。结果:514例高HCY血症人群中,主要以痰湿质(28.2%)、血瘀质(17.1%)、湿热质(14.8%)、阴虚质(12.3%)为主,男性体质分布以痰湿质(32.2%)、血瘀质(16.9%)、湿热质(14.2%)、气虚质(11.2%)为主,女性体质分布以痰湿质(23.9%)、血瘀质(17.4%)、湿热质(15.4%)、阴虚质(14.6%)为主。痰湿质、血瘀质、湿热质、阴虚质的年龄、舒张压、三酰甘油水平比较,差异有统计学意义(P<0.05),其中,痰湿质年龄水平高于其他3种体质,湿热质年龄水平最低(P<0.05);血瘀质舒张压高于其他3种体质(P<0.05),湿热质三酰甘油含量高于其他3种体质(P<0.05)。痰湿质、血瘀质高HCY人群与饮酒有显著相关性(P<0.05),湿热质高HCY人群与高血压有显著相关性(P<0.05),痰湿质、阴虚质高HCY人群与血脂异常有显著相关性(P<0.05)。结论:痰湿质、血瘀质、湿热质、阴虚质是高同型半胱氨酸血症的主要体质,男女体质分布有差异,不同体质相关的危险因素不同。     

Assessment of the Destruction of a Fibre Cement Board Subjected to Fire in a Large-Scale Study

This article presents the results of a study involving the assessment of the structural destruction of fibre cement boards taken from a large-scale model subjected to fire. These were subjected to a three-point bending test using the acoustic emission method. The analysis of the obtained results took into account the course of bending stresses σ_m, the modulus of rupture (MOR), the number of acoustic emission events N_zd and the sum of EA events ∑N_zd. The conducted tests showed that the samples subjected to fire exhibited a clear decrease, up to 72%, in the recorded sum of EA events compared to a reference board (not subjected to fire). The analysis of the obtained modulus of rupture (MOR) values showed a similar trend—the reduction of the modulus of rupture for the degraded samples was in the range of 66–96%. In order to illustrate the changes taking place in the structure of the tested plates more precisely, analyses were carried out using the optical method and a digital microscope. This method may be sufficient for the final evaluation of degraded samples.
