The quality of the cellulose determines the quality of the mortar. What do you think? In the ready-mixed mortar, the amount of cellulose ether added is very low. However, it can significantly improve the performance of wet mortar, which is the main additive that affects…
What about mortar cracks? How to construct? Plastic crack Principle explanation Plastic cracking refers to the cracking of the mortar before or during hardening. It generally occurs in the early stage of mortar hardening. The plastic cracking cracks are generally coarse and the crack length…
The classic three questions and three answers about putty How to deal with the cracking of the putty layer after the putty is put out, what should I do? answer: There are many reasons for the cracking of the putty. There are external reasons and…
Putty/paint construction, high temperature is not afraid For paint applications, high temperatures are definitely not a good thing. Cracking and peeling may occur in the construction under high temperature in summer. This is not necessarily a problem with the product, and it may be caused…
Effect of cellulose on tile adhesive 1 Introduction Cement based tile adhesive is the largest application of special dry mortar. It is an organic or inorganic mixture based on cement. It is the main cementing material, supplemented by graded aggregate, water retention agent, early strength…
Application of Hydroxypropyl Methyl Cellulose (HPMC) in Building Materials Hydroxypropyl methylcellulose (HPMC) is made from natural polymer material cellulose. A nonionic cellulose ether produced by a series of chemical processing. And they are an odorless, tasteless, non-toxic white powder. Swell in cold water into a…
Eighteen questions about mortar technology 1. What materials are used to make building mortar? What is the general use? A: Building mortar is make up of inorganic cementitious materials, fine aggregates and water, sometimes mix with certain admixtures.Construction mortar is often use for masonry (such…
The difference between concrete and mortar What is concrete? Concrete is a solid material form by cement as cementing material, natural sand and stone as aggregate, mixing with water, casting and solidifying. Concrete aggregate The sand is call fine aggregate, and its particle size is…
Small knowledge of crack-resistant mortar Anti-crack mortar, a mortar make of a polymer emulsion and an admixture, which is make of a crack resistant, cement and sand, which is stir at a certain ratio and which can satisfy a certain deformation and maintain no cracking….
Several problems often encountered in dry-mix mortar in engineering applications Dry-mixed mortar is usually called hydraulic cement mixed mortar. It refers to the physical mixing of aggregates (such as quartz sand). inorganic cementitious materials (such as cement) and additives (such as polymers) which are dried…
