A produção de cimento consome muita energia e emite uma quantidade significativa de dióxido de carbono, devido ao calor extremo necessário para o seu fabrico. Além disso, gera quase uma tonelada de dióxido de carbono. Os problemas ambientais associados à eliminação de subprodutos minerais, à energia e ao elevado custo do cimento Portland exigem mais esforços para encontrar substitutos. Estes são chamados de materiais cimentícios suplementares para substituir parte do cimento no betão. As pozolanas artificiais são materiais obtidos por tratamento térmico, tais como sílica ativa, horma, metacaulim, cinza de casca de arroz e diatomita. Os benefícios únicos de tais adições são a necessidade de menos energia para a produção, o aumento da resistência química ao ataque de sulfatos, a impermeabilidade, a redução do calor de hidratação e a expansão térmica das pastas de cimento pozolânico. Os betões que utilizam cimento composto podem ter propriedades desejáveis para fins específicos, tais como evolução de calor total mais lenta e reduzida em estruturas maciças, durabilidade melhorada ou, com microsílica, resistências acima do intervalo normal.
