The Component Analysis of Penetration Sealer Materials

Abstract

Nowadays, its more common of dispensing a topping material like concrete crystalline penetration sealer materials (CSM) onto the surface of a plastic substance such as concrete to extend its service life span by surface protections from outside breakthrough. Its known as the CSM may penetrate into the existing pores or possible cracks in such a way that it may form crystals to block the potential paths which provide breakthrough for any unknown materials. Even though all kinds of test data and researches have been reported to boast of its advantages in both theoretical technologies and application functions, to accept that as an agreed fact, namely the major components and those proportions have not been fully announced in public or research. This study employed various experiments, such as scanning electron microscope (SEM), energy dispersive spectrometer (EDS), X-ray diffraction (XRD), X-ray fluorescence (XRF) and Fourier transform infrared spectroscopy (FT-IR), to identify key components of CSM for developing another type of CSM so that its components could be open for the public. There are two types of commercial CSM adopted for the tests and then thru a series of discusses of test results the most possible components of CSM are proposed as a future reference of CSM related researches.

A Study of Crystalline Mechanism of Penetration Sealer Materials

“…The photos of before, during and after hydration show the formation of hydrate for water/CPSM ratio 2/5 by weight as in Figure 1A –C, wherein Figure 1A,B indicate without and with water; Figure 1C shows the white crystals appear at the top of the sample after 24 h of hydration. It is necessary to point out that the previous study [ 11 ] had investigated two commercial products of CPSM and then proposed a list of components for one kind of similar CPSM, which are the same components used here to produce all of these CPSM test samples.…”

“…In addition, the previous study [ 11 ] reveals high similarity between CPSM and cement; hence, the CPSM samples should be kept moist for at least seven days while curing to develop those acicular-like crystals to achieve their maximum intrinsic rigidity. Furthermore, Figure 11 illustrates the partial CPSM (No.…”

“…Therefore, we performed a complete product evaluation to gain knowledge of a product for those of commercial CPSM. A similar product of CPSM had been proposed in a previous article [11]. As discussed in this article, the laboratory set up a test plan to perform a series of experimental tests on samples to determine if they contain crystalline penetration, what kind of crystals those are, whether or not they are capable of sealing pores or cracks and, finally, the depth of crystalline penetrations.…”

Performance Evaluation of Silane in Concrete Bridge Decks Using Transmission X-ray Microscopy

“…TXM is a novel measurement technique that has been used by other researchers for the investigation of transport properties of different systems [3,[37][38][39][40][41][42], but it has not been applied for sealer-coated samples to study and quantify the effectiveness of silanes in reducing salt ingress in order to improve the long-term performance of concrete structures. Other studies that have used X-ray imaging techniques tried to study the presence of silane or to study the penetration depth of the sealers without quantitatively comparing the mass transport properties of coated and uncoated concretes [5,[43][44][45]. This study proposed a simple way to measure the penetration depth of silane.…”

Effect of permeability-reducing admixtures on concrete properties at different cement dosages

“…This reaction produces a modified calcium silicate hydrate and a pore-blocking precipitate. Furthermore, as illustrated in Figure 2, a product of cement hydration can react with Ca(OH)2 to form a C-S-H gel [15].…”
