2012年5月4日 · In this article, by means of physical–mechanical measurements, thermal methods, XRD and SEM, we study the structure and the formation of the newly crystal phases in white SCM, and reveal the influence of marble aggregate, zeolite and polymer admixture on them.

2017年5月12日 · Thermogravimetry (TG) is a widely applied technique for characterization of hydration products in cementitious systems. Measurements of bound water, calcite and portlandite contents by TG are usually reported and used to assess hydration and reaction of cement and supplementary cementitious materials, as well as carbonation progression [1].

2021年7月17日 · The thermal gravimetric analysis (TG) is a common method for the examination of the carbonation progress of cement-based materials. Unfortunately, the thermal properties of some components complicate the evaluation of TG results.

2018年4月30日 · Thermogravimetry (TG) and X-ray diffraction (XRD) are commonly used together to identify and quantify cementitious phases (e.g., hydration products of portland cement) [1], [2], [3], [4] as these techniques are mutually supportive given that (1) TG enables the quantification of non-crystalline phases (e.g., calcium silicate hydrate (C-S-H ...

TG/DTG curve of anhydrous cement. Portland cement containing a fixed amount of mineral admixtures (calcium carbonate or dolomite or magnesite) was hydrated at 60 °C for 7- and 28 days. Phase...

2019年11月1日 · The TG and differential thermogravimetry (TG-DTG) analysis provided useful data on the dehydration and decomposition of CW. The TG and DTG curves of the untreated CW are presented in Fig. 6.

This brief introduces TG/DTA measurement data using Portland cement (NBS: SRM633, JCA(Japan Cement Association): 211M) prepared as a standard. 2. Measurement example. Figure 1 shows the TG & DTG data of each cement sample. Each weight loss is seemed to be as follows: ~ 100oC Dehydration of free water.

2025年1月22日 · To grasp the decomposition reaction rule of calcium carbonate in cement raw material, the thermogravimetric analyzer (TG), derivative thermogravimetric (DTG), and differential scanning calorimeter (DSC) were used for analysis.

Among the alternatives containing SCM, ternary cement (TC) or limestone calcined clay cement was developed. ... This study evaluates the influence of milling on the reactivity of drilling...

TG-DTG curves of hardened cement pastes. The purpose of this paper is to investigate the hydration behavior of hardened Portland cement paste cured in different environmental pH...
