Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
CLC block is a cement-bonded material made by mixing slurry of cement with stable, pre-formed foam manufactured on site. These blocks are light in weight and competitive with red clay bricks in pricing. They offer significant savings for finished structures and provide excellent sound insulation, ukufakwa kwe-thermal, and fire resistance.
The CLC block has many advantages over conventional construction materials such as burnt clay bricks, hollow concrete bricks and fly ash bricks. These advantages include the low density, lower cement and aggregate content in the mixture, ukufakwa kwe-thermal, and sound suppression.
In this research, a series of different CLC bricks with variable composition were tested to evaluate their strength and density. The test included compressive strength at three ages, namely 3, 7, 14 kwaye 28 days after curing.
Iziphumo zibonise ukuba amandla oxinzelelo lwe-CLC ayephezulu xa i-OPF kunye ne-BC zixutywe kwi-CLC kune-CLC eqhelekileyo. I-OPF ibe negalelo ekunciphiseni isithuba somoya ngaphakathi kwisampulu, ngelixa i-BC isebenza njengesihluzo phakathi kwesanti kunye nesamente. Ukwengeza, I-BC ifunxa amanzi ngokwawo kwaye iwakhuphe kancinci kwi-CLC kwaye iphucule ukusabela kwe-hydration.
Indibaniselwano ye-OPF kunye ne-BC ikwanyusa ukomelela kokwahlulahlula kwe-CLC. Ngaphezu koko, i-OPF kunye ne-BC indibaniselwano yandise ukuxinwa okomileyo kwe-CLC ngokunciphisa i-air void kwi-CLC. I-OPF kunye ne-BC indibaniselwano nayo yakwazi ukugcina ingxinano efanayo ye-CLC njenge-CLC eqhelekileyo kunye nomlinganiselo ofanayo we-BC kumxube..
