Definitions
- the present invention relates to a method for manufacturing of supplementary cementitious materials (SCMs), i.e
- Fly ash is a supplementary cementitious material, which is useful for production of concretes, mortars and other mix ⁇ tures comprising cement. Fly ash is a by-product of coal burning power plants and is produced worldwide in large quan ⁇ tities each year.
- Fly ash usually contains about 85% glassy, amorphous compo ⁇ nents in the form of cenosphere particles. According to ASTM C 618 fly ash is classified in two classes, Class C and Class F.
- the Class F fly ash typically contains more than 70% by weight of silica, alumina, and ferric oxides, while Class C typically contains between 70% and 50%.
- Class F is produced as a by product of the combustion of bituminous coal.
- Class C fly ash has a higher calcium content and is produced as a by ⁇ product of the combustion of sub-bituminous coal.
- Serious problems are also related to the stability of fly ash performance.
- Natural pozzolans belong to materials of volcanic origin and sedimentary origin, such as diatomaceous earth. According to ASTM C 618 they are designated Class N pozzolans. The natural pozzolans are described in ACI 232.1R-00 as "Raw or
- calcinated natural pozzolans that comply with the applicable requirements for the class herein, such as some diatomaceous earth; opaline chert and shales; tuffs and volcanic ashes or pumicites, any of which may or may not be processed calcina ⁇ tions; and various materials requiring calcination to induce satisfactory properties, such as some clays or shales.”
- the microstructure of natural pozzolan particles is charac ⁇ terized by high porosity, which significantly increases water demand of concrete mixes containing natural pozzolans to achieve required flowability/workability of the concrete.
- increases in water demand lead to unsatisfactory compressive strength development.
- Chemically active miner ⁇ als usually contain amorphous materials (e.g. amorphous sili ⁇ con dioxide) , which react with calcium hydroxide released during Portland cement hydration (pozzolanic reaction) and form calcium-silicate-hydrate gel [C-H-S gel] - a product similar to the resulting product of Portland cement hydra ⁇ tion.
- amorphous materials e.g. amorphous sili ⁇ con dioxide
- the present invention solves the problem of using natural pozzolans in concrete.
- the present invention thus refers to a method for manufactur ⁇ ing of supplementary cementitious materials for replacement of Portland cement in production of mortars and concretes, where the cementitious materials comprises natural pozzolans in the form of rocks and ashes and sedimentary origin, such as diatomaceous earth.
- the invention is characterized in, that the said pozzolans in crushed state are subjected to a high energetic mechanical processing by means of grinding in a grinding equipment, whereby the pozzolan particles receive mechanical impulses, and in that the grinding is carried out for a predetermined time resulting in a compressive strength of a 2 inch side cube of mortar comprising 80 % Portland cement and 20 % natural pozzolan in a ratio of 1:2.75 to standard sand and in addition water required to obtain a flow of the mortar according to American standard ASTM C 109, which has been properly compacted under vibration and hardened at + 20 °C in sealed condition, which after 28 days is ⁇ 75 % of the compressive strength of a 2 inch side cube, treated as said cube, of a mortar comprising a ratio of Portland cement: sand of 1:2.75 and in addition water corresponding to 48.5 % of the weight of Portland cement.
- the invention refers to a method for manufacturing of supple ⁇ mentary cementitious materials for replacement of Portland cement in production of mortars and concretes, where the cementitious materials comprises natural pozzolans in the form of rocks and ashes of volcanic origin and sedimentary origin, such as diatomaceous earth.
- the said pozzolans in a crushed state are subjected to a high energetic mechanical processing by means of grinding in a grinding equipment, whereby the pozzolan particles receive mechanical impulses.
- the grinding leads to modification of its surface properties in the form of surface porosity reduction and improvement of its chemical reactivity with alkaline medium produced by hydrating cement. It has been observed that the treatment of the pozzolan particles gives that there occurs local melting of the surface of the particals, whereby zones with a high degree of amorphization are created. By this treatment it has shown that natural pozzolans show a surprisingly good effect when the so treated natural pozzolans replace Some of the amount of Portland cement in a cement paste, mortar and con ⁇ crete comprising Portland cement, pozzolans, sand and water.
- the grinding is carried out for a predetermined time resulting in a compressive strength of a 2 inch side cube of mortar comprising 80 % Portland cement and 20 % natural pozzolan in a ratio of 1:2.75 to standard sand and in addition water required to obtain a flow of the mortar according to American standard ASTM C 109, which has been properly compacted under vibration and hardened at + 20 °C in sealed condition, which after 28 days is ⁇ 75 % of the compressive strength of a 2 inch side cube, treated as said cube, of a mortar comprising a ratio of Portland cement: sand of 1:2.75 and in addition water corre ⁇ sponding to 48.5 % of the weight of Portland cement.
- the amount of water required to obtain a flow of the mortar according to ASTM C 109 may vary, but is approximately
- the compressive strength when using natural pozzolan corre ⁇ sponds to the strength which is obtained when fly ash is used together with Portland cement.
- the present invention can be realized with the use of differ ⁇ ent types of grinding equipment such as media milling equip ⁇ ment, e.g. stirred, centrifugal, tumbling ball or non-media milling equipment, e.g. jet, impact, roller with dominating shear mechanical impulses applied to the particles subjected to processing and combined with air classification.
- the pozzolan can be subjected to grinding in a grinding equipment, which is adopted to the open or closed circuit for material being grinded.
- a preferred particle size distribution is:
- Portland cement, fly ash Class F or C, fine quartz, granite quarry fines, fine frac ⁇ tions of recycled concrete or blast furnace slag or its blends are added to the said pozzolan during or after said processing of the pozzolan.
- Portland cement, fly ash Class F or C, fine quartz, granite quarry fines, fine fractions of recycled concrete or blast furnace slag or its blends are subjected to pregriding to achieve fineness with a retention on the sieve of 45 microns which is less than 5%.
- water reduc ⁇ ing agents, set time regulators, and strength accelerating admixtures in powder form are added to the said pozzolan during or after said grinding of the pozzolan.
- replacement of Portland cement by the said pozzolan in concrete or mortar is from 15 to about 70%.
- the pozzolans is subjected to grinding in said grinding equipment to a fineness of the final product with a retention on a sieve 30 microns being less than 5%.
