“…(1) The formation of magnesite and dolomite of systems with LP in MS solution was confirmed by the results of XRD analysis as shown in Fig. 13 (Sirisawat et al 2014). It was found that much more magnesite and dolomite were detected in LP cement paste specimens than in the OPC specimen.…”

“…This is partly because of lower Ca(OH) 2 when comparing between the amount of Ca(OH) 2 in an ILC specimen (ILC10, ILC20) and that of the OPC 1 specimen, as shown in Fig. 4 (Sirisawat et al 2014). The incorporation of limestone also reduces the amount of C 3 A in the ILC.…”

“…(6) and dolomite in Eq. (7) (Sirisawat et al 2014;Sirisawat et al 2013) were also formed in the limestone powder specimens which were exposed to MS solution. Formation of gypsum, magnesite, and dolomite resulted in less weight loss and less severe surface etching of ILC specimens since the formation mitigated the conversion of C-S-H to M-S-H in MS attacking mechanisms.…”

“…The sulfate ions concentration (in ground water) and the Ca(OH) 2 content in the paste of concrete played important roles, and the permeability of concrete was the same [2,[4][5][6][7]. According to ACI 318-11 [8], the suggestion of chapter 4 indicated exposure to various concentration sulfate ion, the mixture must be simultaneously considered the compressive strength, water-to-cementitious ratio, cement type used and pozzolans [9][10][11][12][13][14][15], etc. The effect of global greenhouse gas emission had a serious issue.…”

Abstract. This study mainly adopted densified mixture design algorithm (DMDA) with pozzolans (fly ash and slag), different fineness slag cement (1:1; MF40 and HF40) and Type I cement (E40) to construct the mixtures for w/cm=0.40, and applied ACI 211.1R and Type II cement as control group (CII40, w/c=0.40). Life cycle inventory of LEED suggested by PCA for cementitious materials (kg/m 3 ) contained cement use, CO 2 emission, raw materials, energy consumption, compressive strength, and immersed in different concentration Na 2 SO 4 solution. Results showed cement content, CO 2 emission, raw materials and energy consumption for E40, MF40 and HF40, with respect to CII40, were 14% ~ 26%, 14% ~ 26%, 13% ~ 26% and 17%~28%. At 28 days, compressive strength(all mixtures) were greater than 41MPa. Repeatedly 25 cycles, specimens immersed in 5000ppm Na 2 SO 4 solution and oven-dried at 105 o C, the exterior had no damage, and weight loss (n) and pulse velocity change (nv) were less than -1% and -5%. But in saturated Na 2 SO 4 solution, the n and nv were ranged from -0.91% (E40) to -2.62% (MF40) and -6.7% (E40) to -10.9% (MF40). The exterior had been obviously scaling (chalking) or spalling at the second (CII40), the fifth (MF40 and HF40) and the ninth cycle (E40). The comprehensive evaluation of green options for anti-sulfate indicated that the merits of all mixtures were respectively E40 > HF40 > MF40 > CII40.

In order to understand the influence of seawater corrosion on the mechanical behaviors of cement mortar, uniaxial compression tests were performed on the cement mortar specimens after corrosion in diverse directions. In this study, solutions of NaCl and Na2SO4 were prepared and used to simulate seawater. In addition, the differences of mechanical behaviors of cement mortar specimens after being immersed in solutions in uni‐, bi‐, and triaxial‐directions were also compared. Test results show that the compressive strength of cement mortar after immersed in sodium chloride solution is higher than that in sodium sulfate solution. The peak strain of cement mortar specimen after immersed in sodium chloride solution is lower than that in sodium sulfate solution after unidirection corrosion. Moreover, the compressive strength and peak strain of cement mortar specimen when the loading direction is parallel to the corrosion direction are both higher than those when the loading direction is perpendicular to the corrosion direction.
