Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 06.06.1974 70394 KI. 80b, 3/08 MKP- C04b 7/26 CZY :l^ia Urzedu Patentowego Polnej l2tuyL^ii-;i,.ej Liniowej , Twórcy wynalazku: Aleksander Maciaszek, Stanislaw Oyrzanowski, Antoni Paprocki, Wojciech Roszak Uprawniony z patentu tymczasowego:Instytut Techniki Budowlanej, Warszawa (Polska) Aktywowane spoiwo z popiolów lotnych do zapraw i betonów Przedmiotem wynalazku jest aktywowane spoiwo z popiolów lotnych do zapraw i betonów.Znane sa dotychczas spoiwa wapienno-popiolowe o skladzie 48% popiolów lotnych suchych, 48% wapna niegaszonego i 4% gipsu surowego. Popioly lotne dodaje sie równiez jako wypelniacz do gipsobetonów. Zaprawy wykonane na tych znanych spoiwach maja niewysoka wytrzymalosc na sciskanie rzedu okolo 30—40 kG/cm2, ponadto nie sa odporne na dzialanie wody. Spoiwa wapienno-popiolowe charakteryzuja sie zbyt wolnym czasem twardnienia rzedu 56 dni, natomiast gipsobetony maja zbyt szybki czas wiazania oraz nie wykazuja wzrostu wytrzymalosci w czasie. W zadnym przypadku nie nadaja sie do wykonywania betonów konstrukcyjnych. Zapra¬ wy wykonane przy zastosowaniu spoiwa wapienno-popiolowego jak równiez gipsobetony odznaczaja sie nad¬ mierna nasiakliwoscia, która powoduje zmniejszenie wytrzymalosci w czasie ich eksploatacji.Celem wynalazku jest unikniecie podanych wyzej wad i niedogodnosci przez zwiekszenie odpornosci spoiwa na dzialanie wody oraz wytrzymalosci w ciagu 28 dni i dalszego wzrostu wytrzymalosci w czasie. Dla osiagniecia tego celu zostalo postawione zadanie opracowania skladu spoiwa, który zapewnialby pozadane wlasciwosci.Zgodnie z wynalazkiem spoiwo z popiolów lotnych do zapraw i betonów sklada sie z 5,00—20,00% wago¬ wych cementu, 8,00—10,00% wagowych wapna, 6,99-9,90% wagowych gipsu, 5,00% wagowych piasku, 60,00-70,00% wagowych popiolów lotnych siarczanowo-glinowych lub krzemianowo-glinowych lub ich miesza¬ niny i 0,01-0,10% wagowego soli metali ziem alkalicznych.Zaprawa normowa wykonana na spoiwie wedlug wynalazku odznacza sie wytrzymaloscia po 28 dniach na zginanie okolo 50 kG/cm2, na sciskanie okolo 200 kG/cm2 i wyraznym wzrostem wytrzymalosci w czasie.Spoiwo wedlug wynalazku nadaje sie zatem do wykonywania zapraw i betonów samonosnych lub wypelnia¬ jacych. Ponadto spoiwo to mozna zaliczyc do spoiw hydraulicznych, gdyz wiaze w wodzie i jest odporne na jej dzialanie. Zaprawa wykonana na spoiwie wedlug wynalazku wykazuje niewielki skurcz, nie odbiegajacy od skurczu normowych zapraw cementowych i bardzo duza szczelnosc.2 70 394 Elementy wykonane przy zastosowaniu spoiwa wedlug wynalazku charakteryzuja sie calkowita mrozood¬ pornoscia i niewielka scieralnoscia. Zaprawa wykonana na spoiwie wedlug wynalazku jest latwo urabialna bez dodatku srodków uplastyczniajacych, co stanowi szczególnie wazna ceche przy zaformowaniu elementu. Rów¬ niez zaleta spoiwa wedlug wynalazku jest latwosc rozformowywania elementów po kilku godzinach od zaformo- wania i mozliwosc ich transportu po 24 godzinach. Stosowany jako aktywator w spoiwie wedlug wynalazku cement portlandzki mozna zastapic cementem hutniczym. Ponizej podano przyklady skladu spoiwa wedlug wynalazku Przyklad.

PLPriority: Application announced: May 30, 1973 Patent description was published: June 6, 1974 70394 KI. 80b, 3/08 MKP- C04b 7/26 IF: l ^ ia of the Patent Office of Polna l2tuyL ^ ii-; i, .ej Linowa, Inventors: Aleksander Maciaszek, Stanislaw Oyrzanowski, Antoni Paprocki, Wojciech Roszak Authorized by a temporary patent: Institute Techniki Budowlanej, Warsaw (Poland) Activated fly ash binder for mortars and concrete The subject of the invention is activated fly ash binder for mortars and concretes. Lime-ash binders with the composition of 48% dry fly ash, 48% quick lime and 4 % raw gypsum. Fly ash is also added as a filler for gypsum concrete. Mortars made on these known binders have a low compressive strength of about 30-40 kgf / cm2, moreover, they are not resistant to water. Lime-ash binders are characterized by a too slow hardening time of 56 days, while gypsum concrete sets have too fast setting time and do not show any increase in strength over time. In no case are they suitable for making construction concretes. Mortars made with the use of lime-ash binder as well as gypsum concrete are characterized by excessive absorptivity, which reduces their strength during their operation. days and a further increase in endurance over time. In order to achieve this goal, the task of developing a binder composition that would provide the desired properties was set. According to the invention, the fly ash binder for mortars and concrete consists of 5.00-20.00% by weight of cement, 8.00-10.00 % by weight of lime, 6.99-9.90% by weight of gypsum, 5.00% by weight of sand, 60.00-70.00% by weight of volatile alumina-aluminum or silicate-aluminum ashes or a mixture thereof, and 0.01- 0.10% by weight of alkaline earth metal salts. The standard mortar made on the binder according to the invention is characterized by a bending strength of about 50 kg / cm2 after 28 days, a compressive strength of about 200 kg / cm2 and a marked increase in strength over time. therefore for the production of self-supporting or filled mortars and concretes. In addition, this binder can be classified as hydraulic binders as it binds in water and is resistant to water. The mortar made on the binder according to the invention shows a low shrinkage, not deviating from the contraction of standard cement mortars, and very high tightness.2 70 394 The elements made with the use of the binder according to the invention are characterized by complete frost resistance and low abrasion. The mortar made on the binder according to the invention is easily workable without the addition of plasticizing agents, which is a particularly important feature when forming the element. Another advantage of the binder according to the invention is the ease of demoulding the elements a few hours after forming and the possibility of their transport after 24 hours. The Portland cement used as an activator in the binder according to the invention can be replaced by a metallurgical cement. Examples of the composition of the binder according to the invention are given below. I. Cement Lime - Gypsum Sand Fly ash Calcium cyanamide Example II Cement Lime Gps Sand Fly ash Magnesium chloride 18.00% by weight 10.00% by weight 6.99% by weight 5.00% by weight 60.00% by weight 0.01% by weight 15.00% by weight 8.00 by weight 7.00% by weight 5.00% by weight 64.90% by weight 0.10% by weight The binder according to the invention is prepared by subjecting the abovementioned ingredients to be ground in ball mills for approximately 1.0-1, 5 hours PL
