For your reinforced concrete <br />building projects <br />SCHOMBURG offers its customers a comprehensive range of sealing solutions. From cementitious <br />mineral and bituminous waterproofing to integral crystalline waterproofing of concrete building <br />components and membrane waterproofing, for example with fresh concrete composite systems. <br />In terms of cost-effectiveness and the improvement in building component properties, the integral <br />concrete waterproofing with the crystalline concrete admixture BETOCRETE certainly stands <br />out. When using BETOCRETE products, the cracks in a “watertight” concrete can grow closed <br />due to the increased and accelerated crack healing ability on contact with water. In addition, <br />the concrete becomes “more resistant” to attacks from the environment and the service life <br />of the concrete building component is noticeably extended. <br />This brochure explains the background and effects.

If the concrete building <br />component is exposed to water, the water is partially absorbed. The extent <br />depends on the water pressure on the one hand and the concrete recipe on <br />the other.</p> <p>outwards <br />(waterside)</p> <p>reinforcing steel</p> <p>reinforcing steel</p> <p>pressurised water zone</p> <p>watertight concrete</p> <p>inwards <br />(airside)</p> <p>moisture <br />release</p> <p>capillary <br />zone</p> <p>core region</p> <p>diffusion <br />region</p> <p>Graphic showing principle of capillary water absorption of a watertight concrete building component.</p> <p>4</p> <p>schomburg.com</p> <p>Cracks in concrete</p> <p>1</p> <p>Cracks can affect the load-bearing capacity, serviceability and durability of concrete building <br />components. Cracks cannot generally be avoided, but they are not fundamentally detrimental either. <br />The width of the cracks only has to be limited to a harmless level or the crack has to be closed as <br />planned. <br />Cracks and crack widths are planned during construction and dimensioning in accordance <br />with DIN EN 1990 (EUROCODE 2).</p> <p>Generation of cracks</p> <p>1</p> <p>Cracks in the fresh concrete are caused by the rapid reduction in volume of the concrete layer near <br />the surface as a result of dehydration. This drying out is favoured by low humidity, wind, solar radiation <br />and unfavourable temperatures. <br />Cracks in ‘green’ and hardened concrete occur when the tensile stresses caused by internal stresses, <br />constraint and external loads reach the tensile strength of the concrete up to that point in time or <br />the strains caused by this exceed the current tensile strains at fracture.</p> <p>Crack types <br />A distinction is made between near-surface cracks and separating cracks. Cracks close to the surface <br />reduce the coverage of the reinforcing steel by the concrete. Separating cracks go through the building <br />component.</p> <p>Section Section</p> <p>Top View <br />Top View</p> <p>Surface cracks</p> <p>1</p> <p>Section Section</p> <p>Top View <br />Top View</p> <p>Tensile cracks</p> <p>CEMENT data sheet B18 2.2020</p> <p>schomburg.com</p> <p>5</p> <p>Concrete degradation <br />In reinforced concrete, the concrete absorbs the pressure and the reinforcing steel absorbs the tensile <br />forces. The reinforcing steel is protected by the concrete cover and by the alkalinity of the concrete. <br />Oxygen in the presence of water oxidises the reinforcing steel. As long as the alkalinity of the concrete <br />is > pH 10, the steel is protected from the rusting process. Chloride ions (XD, XS) accelerate <br />the oxidation process. Oxidation of the reinforcing steel leads to an increase in volume, cracking and <br />the concrete cover flaking off. <br />CO2 in the presence of water leads to a decrease in the pH of the concrete through carbonation (XC). <br />If the pH falls below 10, oxidation processes can progress. The presence of chloride ions accelerates <br />this depassivation process. <br />CO</p> <p>-</p> <p>CI</p> <p>FE(OH)2</p> <p>2</p> <p>H2O</p> <p>2(OH)-</p> <p>Fe2+</p> <p>H₂O+½ O₂</p> <p>2e-</p> <p>Depassivation and oxidation lead to corrosion <br />of the steel reinforcement</p> <p>Concrete cover reduced by freeze-thaw <br />weathering in conjunction with de-icing agents</p> <p>Mechanical (XM) and chemical loading (XA) can attack the concrete cover. Likewise, <br />freeze-thaw cycles (XF) have an effect in connection with de-icing agents.</p> <p>Concrete protection <br />Reinforced concrete can be protected and its service life extended as follows: <br />Keep pH high = A high pH protects the reinforcement steel <br />Reduce water ingress = Lower water ingress means lower input of concrete-damaging <br />substances (CO2, O2, chloride etc.) <br />Reduce chloride ion migration = processes of oxidation and depassivation take <br />place more slowly <br />Protect concrete cover = The higher the concrete cover, the better the reinforcing steel <br />is protected against oxidation</p> <p>Exposure classes after EN 206-1 <br />The right choice of exposure classes is decisive for many <br />technical specifications.

This results in an immediate decrease in capillary water absorption by > 50%. <br />The concrete becomes more waterproof. <br />In addition, when exposed to water, crystals form in the capillary pores and cracks due to increased and <br />accelerated crack healing. The negative effect of water ingress, even in unavoidable cracks, does not occur.</p> <p>2 in 1 / BETOCRETE with integrated <br />concrete admixtures after DIN EN 934-2 (CE) <br />• Concrete after DIN EN 206, which is ordered according <br />to properties, may contain concrete admixtures according to <br />DIN EN 934-2 and the concrete manufacturer assumes <br />the guarantee for the concrete. In the case of admixtures without <br />a CE marks after DIN EN 934-2, a concrete composition would <br />result and the responsibility would pass to the customer. <br />• The sealants integrated in the BETOCRETE provide immediate <br />hydrophobicity in the hardened concrete. With the water contact, <br />crystals then form in pores and cracks (hydrophilic) as an <br />additional effect. <br />• The plasticizer integrated in the BETOCRETE-CL170-P reduces <br />the water/cement value and contributes to a smoother concrete <br />consistency.</p> <p>Cost effectiveness of BETOCRETE waterproofing system <br />• The waterproofing with BETOCRETE becomes an integral part <br />of the concrete construction component as early as during <br />the production of the concrete in the concrete plant. <br />• Subsequent liquid waterproofing can be omitted and does <br />not have to be organised, carried out and monitored on site. <br />• Crack injections for non-dynamic separating cracks up to 0.4 mm <br />can often be omitted due to the crack-healing ability of <br />BETOCRETE concrete. <br />• BETOCRETE waterproofing works for a component's lifetime. <br />Renovation cycles can be eliminated.</p> <p>10 schomburg.com</p> <p>Guide to BETOCRETE concrete formulations</p> <p>Requirements <br />for the concrete* <br />Cement content</p> <p>Min. 270 kg/m3 CEM I; 290 kg/m3 CEM II; 380 kg/m3 CEM III/A</p> <p>Fly ash</p> <p>Max. 80 kg/m³</p> <p>Granulated slag</p> <p>Max. 100 kg/m³</p> <p>w/c ratio</p> <p>< 0.55</p> <p>Grain size</p> <p>16 mm, in exceptional cases 32 mm</p> <p>Construction <br />component thickness</p> <p>The construction component thickness should not be less than 15 cm</p> <p>* Depending on the necessary exposure class and the proportion of fly ash and/or granulated slag. <br />Further information can be found in the current technical data sheet.</p> <p>BETOCRETE® <br />CP</p> <p>BETOCRETE® <br />CL</p> <p>Dosing*: w/c ratio <br />< 0.4</p> <p>0.75 % relative to CEM</p> <p>1.75 % relative to CEM</p> <p>> 0.4–0.5</p> <p>0.80 % relative to CEM</p> <p>1.85 % relative to CEM</p> <p>> 0.5–0.55</p> <p>0.95 % relative to CEM</p> <p>2.00 % relative to CEM</p> <p>In concrete factory</p> <p>BETOCRETE-CP must be dosed onto <br />the aggregates and mixed for at least <br />30 seconds before adding the water <br />and cement.
