Definitions
- the invention relates to a composite material made of cement stone and reinforcement.
- reinforced concrete is indispensable for construction in its current form.
- the concrete absorbs compressive stresses, while the steel reinforcement inserts are responsible for dissipating tensile forces.
- the concrete protects the steel from corrosion.
- This corrosion protection is based on a very high pH value in the pore solution of concrete. From a pH value of around 11, normal reinforcing steel no longer rusts, since very thin passivation layers form on the surface, which seal the steel surface against the ingress of oxygen and water and thus prevent corrosion.
- the pore solution of concretes that are produced with cements according to DIN EN 197, there are pH values above 12.5 and accordingly the use of these cements represents an effective corrosion protection for steel reinforcement.
- the composite building material reinforced concrete has a high performance and durability with low costs and is often used for these reasons.
- the production of reinforcing steel is associated with high environmental impacts and this includes high CO2 emissions in the production of pig iron and steel.
- DE 2409231 A1 discloses the use of mineral fibers with an inorganic binder such as cement. In order to avoid the problems described above, it is proposed to lower the pH value by additional treatment with CO2.
- US Pat. No. 5,002,610 discloses a binder based on magnesium oxide and aluminum phosphate, which hardens very quickly.
- the manufacturing process is extremely complicated and requires multiple drying and grinding and re-mixing of various ingredients.
- the invention is therefore based on the task of specifying a composite material that can have carbon fibers, glass fibers, but also steel reinforcements as reinforcement.
- this object is achieved by a composite material having the features of claim 1 .
- the composite material according to the invention has cement stone made from MgO- and/or olivine-based binders.
- the olivine-based binders use as a starting material a source of forsterite in the form of a natural or artificial source of olivine and/or in the form of tempered serpentinite.
- tempered serpentinite can be understood in particular as serpentinite which has been heated to a temperature of at least 500.degree. Instead of the technical term “annealed” the term "calcined" is often used.
- the composite material according to the invention has reinforcement means to increase the load-bearing capacity.
- these reinforcements are resistant to pH values below 11, have protection against pH values below 11 and/or the MgO and/or the olivine-based binder of the cement stone are means for raising the pH value of the pore solution of the cement stone added to a pH of at or above 11.
- at least one of the above three conditions is provided according to the invention.
- a basic idea of the invention can be seen as deviating from known Portland cement-based cements, which have a relatively high pH.
- the pore solution of a cement stone made from MgO or an olivine-based binder, as understood according to the invention usually has pH values below 11.
- armor made of glass fibers or carbon fibers or combinations of both can be used, which are not stable to media at pH values above 11 without extensive treatment.
- MgO and/or olivine-based binder can be added to the MgO and/or olivine-based binder.
- slaked lime, quicklime, alkalis such as sodium hydroxide or potash
- AMENDED SHEET (ARTICLE 19) umhydroxid, CKD (cement kiln dust, kiln dust from cement production) can be added.
- the starting product should be free from alite and belite, since these can cause hardening problems.
- a production process for cement stone from an MgO- and/or olivine-based binder is described, for example, in PCT/EP2021/061726.
- the pore solution of the cement stone has a pH of 11 or lower. This is particularly the case when the cement stone according to the invention consists of an MgO- and/or olivine-based binder. In this way, no further adjustments need to be made to the raw material of the cement paste for use with glass fiber and/or carbon fiber reinforcement.
- the MgO or olivine-based binder is MgO and SiO2, MgO and MgCOs, MgO and ground glass, olivine and SiO2, olivine and ground glass, olivine and trass, olivine and pozzolan, tempered serpentinite and SiO2, tempered serpentinite and ground glass and/or or individually or combinations thereof.
- Trass is a natural pozzolan, which mainly consists of silicon and aluminum compounds.
- Pozzolan are artificial or natural rocks made of silicon dioxide, alumina, limestone, iron oxide and alkaline substances, which are usually formed under the influence of heat. In connection with calcium hydroxide and water, they are capable of binding.
- any reinforcement means can be used according to the invention.
- the reinforcement means have carbon or carbon and/or glass fibers. Compared to conventional steel reinforcement, these fibers have the advantage that they are lighter on the one hand and significantly less CO2 is produced during their production on the other.
- AMENDED SHEET (ARTICLE 19) It is advantageous if the reinforcement means are designed without a protective layer to resist pH values below 11. This is particularly possible with reinforcement made of carbon and/or glass fiber. In principle, however, a protective layer against such low pH values can also be applied.
- the carbon and/or glass fibers are designed in the form of fiber reinforcements, mat reinforcements, rod reinforcements and other forms of reinforcement.
- the advantage of using carbon and/or glass fibers is that they can be shaped into any shape and then used to produce the composite material. In this way, depending on the expected load, an optimal form of the reinforcement can be provided.
- steel reinforcements can also be present in the composite material according to the invention as an alternative or in addition. If these are used, it is preferable to add Portland cement clinker in particular to the cement paste in addition to the MgO- and/or olivine-based binder. This is particularly suitable for increasing the pH value so that corrosion of steel reinforcement due to the low pH value is prevented. In addition, Portland cement clinker offers the advantage of making its own separate contribution to strength compared to other substances that affect pH.
- the reinforcement means have at least one protective layer to protect against an alkaline environment with a pH value of less than 11.
- This protective layer can be applied, for example, by applying paint and/or varnish.
- the protective layer can be plastic based. Another option is to apply hot-dip galvanizing to steel reinforcement.
- a binder made of pure synthetic forsterite without foreign ions was analyzed.
- a 2:1 mixture of forsterite and fused silica was used to make the cement paste of the composite. After half a year of hydration, the pH value in the first sample was 9.5 and in the second sample the pH value was even in the range of 8.2.
- a binder for a composite material can be produced which has a very low pH value compared to cement paste made from classic Portland cement clinker. Due to this low pH value, glass and/or carbon fiber reinforcements can be used for the first time without further pre-treatment.
