If we ask random people a question about the most valuable raw materials in the world, hardly a few of them will point to sand. Sand is very undervalued, and it is on it that almost the entire construction industry is based. At first glance, it can be touched anywhere, but in practice this material must meet very high requirements so that it can be used for the manufacture of building mortars. What should I keep in mind?Sand for building mortars
What type of sand we will use in the production of mortars will be of great importance for the quality of the final product and, ultimately, for the durability of the structure performed with their help. For the manufacture of building mortars, natural quartz sand or sand obtained as a result of the destruction of rocks such as granite or basalt can be used. The origin of the sand is not as important as its purity-it should not be used for masonry mortar aggregates that carry traces of impurities, such as particles of clay or plant soil. The second important factor determining the choice of aggregate is its grain size. For cement and cement-lime mortars, it is recommended to use sand up to 2 mm in diameter. For gypsum solutions, a filler with a grain diameter of up to 1 mm is the recommended choice.Sand for plaster
As in the case of masonry mortars, the sand used for plaster must be of high purity. The choice of aggregate grain size depends on the type of plaster we want to obtain. The general rule is that the smoother the plaster should be, the less grain the sand used to make it should have. For smooth walls, it is recommended to use sand with a grain size of less than 1 mm. Sand with a higher gradation will give us a plaster with a more rough, decorative surface.How to store sand?
As we have mentioned several times, the purity of sand is crucial for its quality and, consequently, the quality of the solutions produced from it. That is why it is so important to ensure that the unit we use has as little contact as possible with pollutants, such as various types of dust, which are not enough on the construction site, or with the ground. In practice, this is quite difficult, and we must take into account that at least some of the sand will become contaminated and will not be suitable for use. The proposed solution to the problem is sand supplied in plastic bags. The sturdy packaging makes it easier to transport and store sand without worrying about any debris getting into it and that it will lose its usefulness. ১। ক্রিকেট প্রেমীদের জন্য 1xbet প্ল্যাটফর্মে রয়েছে অসংখ্য উত্তেজনাপূর্ণ বাজির সুযোগ। আইপিএল থেকে শুরু করে আন্তর্জাতিক টেস্ট ম্যাচ—প্রতিটি খেলায় আপনি লাইভ বেটিং করে উপভোগ করতে পারেন রোমাঞ্চ। বিশেষ করে যারা নতুন ব্যবহারকারী, তাদের জন্য রয়েছে চমৎকার স্বাগত অফার। আপনি যখন প্রথম অ্যাকাউন্ট খুলবেন এবং জমা করবেন, তখনই পাবেন অতিরিক্ত ফান্ড। এই সুযোগটি কাজে লাগাতে হলে অবশ্যই একটি নির্দিষ্ট কোড ব্যবহার করতে হবে, যা আপনার বোনাস বাড়িয়ে দেবে। 1xbet প্রোমো কোড ব্যবহার করে নিশ্চিত করুন আপনার বোনাস—এখনই সক্রিয় করুন এবং পেয়ে যান ৫০০০ টাকা। এটি শুধু শুরু, এরপর প্রতিটি জমায় মিলবে বিশেষ পুরস্কার। ক্যাশব্যাক, ফ্রিবেট, আ
