It is a popular byproduct of the metal casting industry (both ferrous and non-ferrous), where the use of sand as a molding material is a century-old tradition due to some of its specific engineering properties. </p> <p> </p> <p>All the modern-aged foundry sand manufacturers in Egypt use recycling of the sand to reuse it following various production cycles. According to the industry estimates, manufacturers produce more or less 1,00,00,00,000 lakhs tons of foundry sand every year. Among that amount, 4-7% gets discarded each year to be recycled for the production of other products in various industries. </p> <p> </p> <p>Properties of Foundry sand:</p> <p>Silica sand used in the foundries holds supreme quality as IMA-NA (Industrial minerals Association of North America) supplies most of them. Rigidity in showing chemical and physical properties can result in poor quality sand which in turn can cause casting defects. <strong><a title="Foundry Sand – All You Need To Know" href="http://www.sandtechnology.net/foundry-sand.htm" target="_blank">Foundry sand suppliers in Egypt</a></strong> invest specific resources to control the quality issues of their sand systems, and the suppliers perform extensive testing to maintain the consistency level. This ensures the consistency in the compositions of the foundry sand produced and supplied by the individual facility, and this is a great benefit for most of the consumers. The quality of the casting technique is naturally related to the quality of the sand.</p> <p> </p> <p>Foundry sand is mainly a fine aggregate. After getting properly segregated and screened from a range of metal casting ability discards, these sands are generally used in many of the similar applications where there is a need for traditional construction sands.</p> <p> </p> <p>With an engineering lookout, it can be said that foundry sand has a lot of characteristics which make them suitable for a number of applications. </p> <p> </p> <p>Applications of foundry sand:</p> <p>The market applications of foundry sand can be broken down in three groups, which are –</p> <p>1. Construction and highway – construction projects often required granular materials so that the sites can be leveled effectively. These are also used in creating berns and building embankments. Perfectly manufactured foundry sand performs well in cases of preparing bases under roads and paved structures. Flowable fill is another major application of foundry sand which is to control CLSM or controlled low-strength material.</p> <p> </p> <p>2. Aggregate substitutes – in such applications recycled foundry sand is used as a substitute of other good aggregates in any other bounded products. The maximum amount is used in the manufacturing of feedstock and fine aggregate. Foundry sand is also used as a raw material in making the products bricks, ready-mix concrete, blocks, pavers, ceramic tiles, mortars, grouts, etc.</p> <p> </p> <p>3. Manufactured soils – foundry sand is exclusively used in soil blending due to its 3Cs, which are consistency, color, and composition. In urban locations, scientists and experts of the soil who work for various landscaping and nursery companies, manufacture soils with the process of blending a lot of recycled materials and organic substance.</p> <p> </p> <p><strong><a title="Foundry Sand – All You Need To Know" href="http://www.sandtechnology.net/foundry-sand.htm" target="_blank">Foundry sand exporters in Egypt</a></strong> supply the finest quality products to their worldwide clients which are prepared using advanced sieve analysis method.</p> Applications of crushed limestone http://www.sandtechnology.net/blog/applications-of-crushed-limestone_7519.htm Wed, 16 Oct 2019 12:15:33 +0530 <p>It is difficult to find a naturally formed rock that is as versatile as limestone – especially when it is been crushed and screened. This is the reason why contractors throughout an extensive range of industries rely on crushed limestone to complete their various projects. Paired with its durability, strength, and practicality, crushed limestone has become an excellent material for landscaping, home improvement, and construction projects.</p> <p> </p> <p><a title="Applications of crushed limestone" href="http://www.sandtechnology.net/crushed-limestone.htm" target="_blank"><strong>Uses of crushed limestone:</strong></a></p> <p> </p> <p>One would be amazed at the various ways that crushed limestone can be used for either functional or decorative purposes, including:</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used for making concrete –</strong> Concrete is a combination of cement, sand, water, and crushed aggregate. In some cases, contractors choose to use crushed limestone as the aggregate material so as to create a durable and attractive concrete product.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used in road base –</strong> Before roads and highways can be paved and can be strong enough to withstand traffic, their bases should be filled with a reliable aggregate material. Crushed limestone is ideal as it is affordable, reliable and offers a smooth and easy ride.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used in pipe bedding –  </strong>Crushed limestone is often used for bedding underground pipes. The material is an ideal option because it is able to level and support the pipe. Crushed limestone does not expand and contract, preserving the integrity of the pipeline, and it has the ability to insulate the pipe from any soil movement that could occur as a result of moisture, traffic above the pipe or any other soil distress.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used under slab fill –</strong> For new constructions, concrete slabs cannot simply be laid directly on the earth or ground. Instead, a layer of crushed stone is needed to fill the area beneath the slab. This keeps the concrete in level, allows for good drainage, and prevents settlement cracks. Crushed limestone aggregate is commonly selected for this purpose.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used as flux stone –</strong> When crushed, lime can be used for smelting and other metal refining processes. </p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used in driveways –</strong> Some people like the idea of a gravel driveway, but would prefer to have other color options. Crushed limestone offers all of the benefits of gravel and also provides a soothing, natural tan coloration.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used in railroad ballast – </strong>Railroad ballast supports the rail ties and allows water to flow away from the tracks. Good railroad ballast must be angular and durable, which is why crushed limestone is often chosen.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used as roofing granules – </strong>Crushed limestone is often used as a coating for asphalt-impregnated shingles and roofing. Crushed limestone helps to deflect heat and to protect roofing against the elements. </p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used as rip rap stone– </strong>As it’s affordable, convenient, and reliable, crushed limestone works well as rip rap stone and effectively prevents shore erosion.</p> <p> </p> <p><strong>•<span style="white-space: pre;"> </span>Used as agricultural lime (Aglime) – </strong>Crushed limestone can be used to regulate soil pH levels. Farmers often utilize crushed limestone to improve conditions for crop growing. </p> <p> </p> <p>There are many crushed limestone suppliers in the global market, instrumental in providing supreme quality of crushed limestone. <strong><a title="Applications of crushed limestone" href="http://www.sandtechnology.net/crushed-limestone.htm" target="_blank">Crushed limestone suppliers in Egypt</a></strong> are also famous for presenting the extremely good quality product, procuring the entire range from the trustworthy vendor or <strong><a title="Applications of crushed limestone" href="http://www.sandtechnology.net/crushed-limestone.htm" target="_blank">crushed limestone manufacturer in Egypt</a></strong> and are able to supply the unparalleled quality product to their esteemed patrons.
