Everyone in the world is writing and proving that we have a global problem with our sand resources and that this problem gets worse. The construction boom is continuing worldwide and many Arab and Asian countries are lacking in sand. Sand prices are rising faster in some countries than energy prices.
There are holes dug in the earth, beaches dredged empty, sandbanks and coral reefs sucked, rivers dredged empty, already sucked in deep to 150 meters for sand, some island in the Indian Ocean are already gone because of the beautiful sand for the construction industry, huge ships transport sand across the seas.
Based on decades of experience in the development and application of
UHPC binders based on nanotechnology, we have developed a new generation of
UHPC binders to produce high quality concrete with the addition of natural desert sand.
In standard stress tests with UHPC desert sand binders, compressive strengths of 70 - 100 MPa / 10150 - 14500 psi were measured.
Only UHPC Binder + Desert Sand + Water was used in this tests.
Cast binder and mortar binder qualities were tested.
Today we produce for many international customers UHPC desert cement binder in our production in Germany.
Our UHPC desert sand concrete qualities have a compressive strength between 50 MPa/7250 psi and 100 MPa/14500psi

Thank you for proving desert sand is not useless in concrete applications I was watching PBS program saying desert sand is useless, in construiction computers and metalurgy which is absolute nonsense to create a supply and demand blockade.

Чтобы не ждать полдня один замес, то сначала приготавливается цементное тесто( намного быстрее перемешивается с водой и хим. добавкой) и уже в ньютоновскую жидкость кидаем песок, и очень быстро он вмешается.

Very good material。the mixer is small, we make truck-mounted UHPC mixing plant, 5-13 cubic meters per hour, a vertical shaft planetary mixer, with diesel power and weighing. perfectly worked

how to prevent forming balls during mixing. what is the correct sequence of pouring raw materials and effective time of mixing

Well is sand desert different than sand used in construction , we in Indonesia often mixing cement and sand for concrete .

Hello I'm a civil engineer I want to research on topic how we can use desert sand in concrete. Can you provide more information about this

hey atique, I have a thesis reattach on this topic, if you can provide me with any info you got on how to use desert sand that would be of much help.

Hello, could you tell me please 1) what is the early strength you have for UPHC 100 mpa? 2) How much cement do you put there? Do you sell dry mix of UHPC from Germany?

Hello Roman, Here are my answers to your questions: 1) What is the early strength you have for UPHC 100 mpa? Most of our UHPC material qualities reach 70% of their max. Resistance after less than 48 hours. We also have Rapid UHPC grades that reach their rated strengths much faster. In addition, we can adjust the strength development on customer request during production of the UHPC binder. 2) How much cement do you put there? What I can tell you is that our UHPC definitely includes cement, microsilica and superplasticizer. How much and in what quality is our trade secret. 3) Do you sell dry mix of UHPC from Germany? Yes, we manufacture our UHPC products in Germany. Next year, new production facilities will be built in other countries.

@@paulhyper2185 Dear Paul, thank you for the reply. From your description I understand that you bring desert sand to Germany and produce UHPC there. I assume it add up extra costs to the final product. May I ask you why don't you use some stone artificial sand available in Germany or neighboring countries?
@paulhyper2185
@paulhyper2185 5 лет назад
@@rheocoreoncrete7673 We do not bring desert sand to Europe. In the first stage of development were we are now, we produce the UHPC desert sand binder in Europe and sending the binder worldwide to customers who have come across desert sand. In the second expansion stage, we will install UHPC desert sand binder production facilities on site in the countries with desert sand deposits.

Water in first will stop the balls forming.
@Everfalling
@Everfalling 3 года назад
No, water first makes partially saturated balls of material that are difficult to break up and mix because they slide past each other. Similar balls in a dry mixture will help themselves break up with enough mixing
