MORTAR USING ACTIVATED PARTICULATE MATERIALS

Hereinafter, according to the present invention with reference to a drawing using active powder dry mortar through a browser substrate.

To the present invention activated powder has a positive number, fly ash and the ash residue number is activated, the vibrating with wheat comminuted fly ash (positive number, residue) 30 - 90 minutes, 5 - 15 wt % 5 - 15 wt % on the outside it will do with the ash to the ash number the number 100 wt % anhydrite and mixing in 3 - 10 minutes after vibration mill grinding hydration be mechanically activating other. The anhydrite and gypsum instead, using gypsum disapproval.

General domestic building floor mortar blended in such a proportion (Ref.) (stage, mixing number ratio is adjusted upwards 2 ∼ 3%) precursor to the table 2, the ash and fly ash residue number number/physical properties analysis and evaluation also substituted with positive activity was used.

Table 2 positive number/10 wt % or 20 wt % 0.50 to the fly ash residue substituted such as activity, which was used by substituting a number 10 wt % active. 20 wt % fly ash (AFA) (A2, A3) is fly ash (FA) existing in active positive number positive number 10 wt % 10 wt % + (A2) substituted active 20 wt % 0 wt % + positive number (A3) fly ash or existing fly ash fly ash tree within a combining active, 20 wt % 10 wt % 10 wt % + existing fly ash residue at the time of active residue (ARFA) fly ash (B2) or existing fly ash residue substituted fly ash (B3) 20 wt % 0 wt % + combining active active fly ash was the lower end of the reference. The active number 10 wt % 0 wt % + (C1) existing on the face of the ash (APA) fly ash the ash 10 wt % 10 wt % + active number (C2) conditions existing ash fly ash are no active number front and rear.

Positive number/activeResidueFly ash The number and active Ash 10 wt % of compression strength analysis using mortar

Table 2 hereinafter as chronic mortar prepared by the number of compression strength such as is described substrate.

The general bottom mortar (Ref.) 3 14 one mode of compression strength. 6 mpa, 7 21 during curing. 6 mpa are disclosed.

Also the present invention is characterized in that Figure 1 shows a positive number represents a compression of 10 wt % fly ash using mortar (A1) steel are disclosed. One mode 3 15 as shown. 8 mpa, 7 23 during curing. 1 mpa are disclosed.

In addition, fly ash (crushing) blended with 10 wt % 10 wt % fly ash on active positive number existing mortar (A2) is shown in one mode as also 2 3 12. 0 mpa, 7 19 during curing. 3 mpa are disclosed.

I.e., Ref. 10 wt % fly ash (A1) used compression strength ratio active positive number contrast when most transmission option. Corresponding coordinates (A2) by 10 wt % fly ash when used in each active solidification positive number, i.e. cement content (A1) is active when using fly ash when 10 wt % 10 wt % reduced positive number decreases than a strength ratio is shown. I.e., existing active powder is fixed strength alone 10 wt % fly ash to replace a low thermal conductivity but are derived, by mixing it with existing fly ash (crushing) is fixed shown decreases. Such phenomenon can be active even when used for a fly ash residue as in Figure 2 are expressed.

As shown in fig. 3, in the case of the fly ash is ash active number 10 wt % ash when used in active to replace a number (C1), compressive strength rises is larger when the width, 10 wt % 10 wt % ash (C2) is simultaneously mixing the fly ash on existing active number when existing 10 wt % fly ash (Ref.) similar to a compression intensity values shown in use. I.e., the ash (C2) 10 wt % 10 wt % + 7 compressive strength fly ash up even when existing active number by grouping, i.e. cement 60 wt % reduction in compression strength properties has been confirmed that the difference is not even up to 70 wt %. The reaction of the active number CA crystal contained ash ring person [thu compound according to strength and low thermal conductivity along generating instance's oldest.

In each case, flow value is higher active powder in use some 24.4, general bottom mortar (Ref.) 196 mm min of flow. The ash Ref active number during use. Low flow value-width than precursor, the active number (C1) is 192 mm flow value gata 10 wt % ash in use. The active number Ref and the ash. Flow difference was 4 mm level. (RFA) is not high and the lowest flow is fly ash residue, the flow value is 184 mm min. In addition fly ash (A1) and the highest flow value is positive number is not active, the flow value is 199 mm min.

Positive number/activeResidueFly ash 20 wt % of compression strength analysis using mortar

Figure 4 shows a positive number 20 wt % fly ash and fly ash using compression of each active residue active also represents a steel mortar are disclosed.

Active positive number of compression strength (A3) using mortar (cement 60 wt %) fly ash 20 wt % 10 wt % fly ash (cement 70 wt %) lower than the intensity values using existing mortar shown. (7 curing existing 10 wt % fly ash (Ref.) compression strength: 21. 6 mpa, active positive number 20 wt % fly ash: 19. 9 mpa, active residue fly ash: 19. 3 mpa).

Active positive number when a mutual use 20 wt % active fly ash fly ash residue, mortar compressive strength but similar levels, high-width result value derived active positive number 7 compressive strength fly ash in use been. Positive number solidification 196 mm and 194 mm respectively existing comparable but active flow is fly ash, fly ash residue 189 mm 5 mm reduced [...] ash as compared than in active use. 4 active positive number/20 wt % fly ash residue from initial 3 and 7 also order same as that necessarily identifying capable of substantially enhancing strength.

In the present invention based on the fly ash 10 wt % 10 wt % + 3 also for early strength increase active number of compression strength (C2) (total 20 wt %) existing ash when used in existing similar 10 wt % of compression strength only fly ash as a result, the enhanced early strength properties as well as the mixed ash/active number.

Early strength (AFA)/(ARFA) positive number for increase of active chronic active fly ash (APA) the ash residue number each 5 wt %, 10 wt %, as well as the 15 wt % and a mixing in 20 wt %. 6 activity such as fly ash and active residue number 5 and also the ash fly ash also positive number active when increasing the compressive strenght-width (APA) mixing amount tends updated by precursor, 3 and 7 (cement 70 wt %) 10 wt % fly ash (FA) existing similar compression intensity values used for diagnosing both shown.

The ash residue number 7 and Figure 8 (APA) is also added 5 ∼ 20wt % active positive number/active fly ash exhibits to use mortar flow value. The ash (APA) upon addition of 10 wt % active number increased flow in-width up but, 15 wt % or more but to read, these flow difference extremely disclosed. (200 mm maximum, minimum 195 mm).

Or more from the results of experiments, when the active number added ash, fly ash residue sufficiently early strength of mortar positive number/active will find exercise can be used. I.e., replace existing cement 10 wt % 10 wt % fly ash (FA) in addition further can replace the fatigue strength. (B) when a repository prestressed strength and workability, the optimum condition of active number has been confirmed that the condition that 10 wt % ash were added.
