Utilization of municipal solid waste incineration fly ash (MSWI-FA) can avoid land occupation and environmental risks of landfill. In this paper, MSWI-FA was used to prepare alkali activated cementitious materials (AACMs) after two-step pretreatment. The ash calcination at 450 °C removed 93% of dioxins. The alkali washing with 0.2 g NaOH/g ash removed 89% of chlorine and retained almost 100% of calcium. The initial setting time of AACMs was too short to detect for 20% of MSWI-FA addition, and the prepared block had extensive cracks and expansion for CaClOH and CaSO4 inside. Alkaline washing pretreatment increased the initial setting time by longer than 3 min with 30% ash addition and eliminated the cracks and expansion. The significance of the factors for compressive strength followed the modulus of alkali activator > silica fume amount > alkaline washing MSWI fly ash (AW-MSWI-FA) amount. When the activator modulus was 1.2, 1.4 and 1.6, the blocks with 30% of AW-MSWI-FA had a compressive strength of up to 36.73, 32.61 and 16.06 MPa, meeting MU15 grade. The leaching test shows that these AACM blocks were not hazardous waste and almost no Zn, Cu, Cd, Pb, Ba, Ni, Be and Ag were released in the leaching solution.

“…Secondly, it was left to rest for at least 48 hours to activate the greatest amount of clay particles before kneading. Finally, coarse sand was added, sawdust as identified in figure 1 (B) and EPS shown in figure 1 (C), according to the quantities of the sample to be tested [7]- [30]- [31]. Figure 2 shows the compressive block resistance test.…”

“…|It also has a low density and can easily be separated from other wastes. However, it has little demand for recycling due to its low cost, so we generate an ecological and innovative initiative by reusing it as an addition to the mixture of adobe blocks [7]- [9]. According to the Metropolitan The Public Company for Solid Waste Management of the Metropolitan District of Quito, in October 2013, it carried out the characterization of urban solid wastes, in which it determined the percentages of the average composition of solid wastes, which indicates that the waste of polystyrene has a percentage of 1.132% in the north station and 0.92% in the south station, likewise, the wood waste has 0.833% in the north and 0.877% in the south [10].…”

This experiment evaluates the use of sawdust and expanded polystyrene (EPS) in the elaboration of adobe blocks as thermal and acoustic constructive elements with low environmental impact. To begin with, a soil selection and analysis process were carried out based on E-080 standard, then traditional adobe blocks with a percentage of 5%, 10% and 15% of sawdust and EPS were added in each mix. A suitable chamber was built to carry out the tests, based on specific standards, the chamber was divided into two rooms by a wall of the abode block with the addition of sawdust and expanded polystyrene using a 5mm layer of mortar to correct joint errors, this was considered appropriate for making temperature and sound measurements with the SPARK LXi Data logger (PS-3600A). Based on the Ecuadorian Construction Standard, comfortable reference values were determined for the measurements. After 28-day elaboration, the blocks were tested under compression. This test showed that all the analyzed samples exceeded the minimum resistance of 1MPa established in the E-080 standard. It was the highest compressive strength obtained in blocks with 5% of sawdust and EPS with a maximum resistance of 2.66 MPa. In addition, it was obtained that the wall made of 10% and 15% of adobe sawdust and EPS present the best performance to thermal variation and acoustic conditioning based on the standards NCh 352, NCh 851 -NCh 849 and NCh 2865.
