The average person buying cement and sand is nothing more than two ways: brand supermarkets and building materials markets, brand supermarkets generally have relatively high prices, single varieties, quality guaranteed; the building materials market can buy materials at wholesale prices, and the variety is rich, there can be multiple options For the moment, the choice of the latter is still the majority. Many netizens believe that cement sand can be mixed with what is false? As long as I pay attention to weighing when inspecting, everything is OK, but it is not.

If you are more willing to purchase in the building materials market, we suggest that you first put a question mark in the following three areas:
One: The amount of cement sand is insufficient. At the time of your inquiry, the other party may tell you about the price of 50 kg of cement, and the delivery may be 40 kg of cement.
Two: Does the type of cement sand meet your expectations? Home decoration usually uses ordinary Portland cement, but the merchant may give you other types of cement, such as slag cement.
Three: Cement sand is not genuine. For consumers who do not have professional knowledge, it is difficult to identify authenticity. You can bring experts who are knowledgeable to accompany you.

How can we pick the real cement sand in a mixed market? Don't worry, see what the experts say.
Question one: What kind of cement sand is used in home improvement?
Cement - commonly used cement is classified into 5 types of Portland cement, ordinary portland cement, slag cement, pozzolan cement, and fly ash cement. In the home improvement process, ordinary Portland cement is generally used, and the industry is also called ordinary cement.
According to different strengths, ordinary cement is divided into multiple numbers. Generally, the higher the number, the higher the strength. However, the higher the number does not mean that the better, different projects apply different grade (strength) of cement. For example, if you use an excessively high number of cement when laying tiles, it may cause emptying or even cracking of the tiles. Home interior decoration works usually use the cement labeled 32.5.
Sand - Cement can only be used after blending a certain amount of sand and turning it into cement mortar. The industry usually divides sand into four types: fine sand, fine sand, medium sand, and coarse sand according to specifications. In general, the thicker the sand, the higher the strength of the formulated cement mortar, but if the strength is too high, it will affect the quality of the project, such as cracking the surface leveled with high-strength cement mortar. Home improvement sand is recommended.
Question two: How to identify cement sand?
Cement - When you buy cement, you should start with the appearance, information, reports, and feel.
The appearance looks at the appearance of the cement and its packaging quality. High-quality cement should be gray and white, and generally use moisture-resistant and non-breakable internal film packaging bags; poor quality cement tends to be rough and easily cause moisture to agglomerate. Too much or too much color of the cement indicates too much impurities.
Information refers to the various signs and information on the cement packaging. Cement produced by regular manufacturers should be marked with registered trademarks, origin, production license number, implementation standards, packaging date, bag net weight, factory number, cement varieties, etc., with clear writing and complete content; inferior cement is often deliberately omitted some content, The information on the packaging is also often blurred. If you are not confident about the cement you have purchased, you can also call the manufacturer's phone provided on the package and ask the manufacturer to help identify it.
The report refers to the manufacturer's test report. Consumers can ask the salesman directly and use the inspection report to judge the quality of the cement. In general, the test report will give the identification results of various performance indicators such as cement strength.
In addition to the above method, consumers can also check the quality of cement by their hand. High-quality cement particles are delicate; poor-quality products are rough in hand, and have low strength and poor viscosity when used.
