Diamonds are forever, Gold is precious but which is rarer? Gold is a heavy metal formed during the collision of neutron stars and is one of the rarest elements on Earth.During the formation of the earth, heavy elements gradually accumulated towards the core under the influence of the earth's gravitational force. This means that the closer you get to the Earth's crust, the harder it is to find large quantities of gold.The average concentration of gold in Earth's crust is "very, very low" at just 4 parts per billion. Gold concentrations need to be 1,250 times that level to form a market-worthy deposit.
Diamond is a common element - the product formed by carbon under extremely high pressure, and it is a dense carbon element. Carbon also has a looser element called graphite, which is what makes pencil lead. Compared to gold, the average concentration of carbon in the Earth's crust is about 200,000 parts per billion.
In terms of elements, gold is far rarer than diamonds. Due to the predictable and volatile nature of gold, the low alkali cement is undoubtedly a good investment opportunity.

There are many types of cement, such as low alkali cement, ordinary cement and so on. Do you know the difference between low alkali cement and ordinary cement? What are the precautions for the use of cement?

The difference between low alkali cement and ordinary cement

1. The properties are different. The raw materials of low-alkali cement contain a large amount of blast furnace slag, while the raw materials of ordinary cement are mainly limestone and clay.

2. The characteristics and functions are different. Low-alkali cement is suitable for use in particular areas because the alkalinity is relatively low, while ordinary cement has a broader range of use and higher alkalinity.

Precautions for the use of cement

1. Do not expose to the sun for quick drying

After the construction is completed, attention must be paid to the maintenance of the glue to avoid the evaporation of water too fast, resulting in too fast drying and reducing the strength. The general maintenance time is about seven days.

2. Avoid freezing at a negative temperature

After the concrete is mixed, it cannot be frozen because the temperature is too low. So be sure to choose a suitable temperature environment for construction.

3. Avoid high temperature and heat

If the construction temperature is too high, the calcium hydride in the concrete is easily decomposed, which will lead to the problem of reducing the strength of the concrete. If it needs to be constructed in a high-temperature environment for some special reasons, it is best to add some heat-resistant materials to the concrete, which can increase the strength of the concrete.

4, avoid the base layer from being dirty and soft

Be sure to treat the base layer firmly before construction so that the cement and the foundation will be firmly bonded together during construction. If the construction is on a smooth base surface, the base surface must be brushed so that the cement and the base surface can bond more firmly. In addition, when mixing concrete, be sure to mix evenly so that the concrete setting effect will be better during construction.

Due to the Russia-Ukraine conflict and the covid-19 pandemic, how will the international situation develop is highly uncertain. It is too difficult to assess its economic impact properly. However, we could see energy prices and commodity prices keep rising and supply chains are disrupted. Therefore, low alkali cement prices are expected to rise in the future.
